4492
4493     * configure.ac
4494     Fix bug which occurres when configuring for MinGW.
4495     If compiler is gcc and cross compiling use -nostdinc.
4496
4497 2004-03-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4498
4499     * src/common.h src/aiff.c src/wav.c src/float32.c src/double64.c
4500       src/sndfile.c
4501     Fix a bug with PEAK chunk handling for files with more than 16 channels.
4502     Thanks to Remy Bruno for finding this.
4503
4504 2004-03-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4505
4506     * src/common.c
4507     Fix a bug which was preventing WAV files being openned correctly if the
4508     file had a very large header. Thanks to Eldad Zack for finding this.
4509
4510 2004-03-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4511
4512     * configure.ac src/file_io.c
4513     Fix cross-compiling from Linux to Win32 using the MinGW tools.
4514
4515 2004-03-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4516
4517     * src/create_symbols_file.sh
4518     Christian Weisgerber pointed out that the shell script did not run on a
4519     real Bourne shell although it did run under Bash in Bourne shell mode.
4520
4521     * src/create_symbols_file.py
4522     Rewrite of above in Python. Also add support for writing Win32 .def files.
4523     The Python script generates Symbols.linux, Symbols.darwin and
4524     libsndfile.def (Win32 version). These files get shipped with the tarball
4525     so there should not be necessary to run the Python script when building
4526     the code from the tarball.
4527
4528     * configure.ac src/Makefile.am Win32/Makefile.am
4529     Hook new Python script into the build system.
4530
4531 2004-02-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4532
4533     * src/configure.ac
4534     Add --enable-gcc-werror option and move GCC specific stuff down.
4535
4536 2004-02-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4537
4538     * acinclude.m4 configure.ac
4539     Fix clip mode detection (tested in one of HP's testdrive Itanium II boxes).
4540
4541     * src/file_io.c
4542     Added check for sizeof (off_t) != sizeof (sf_count_t) to prevent recurrence
4543     of missing large file support on Linux and Solaris.
4544
4545 2004-02-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4546
4547     * examples/sndfile-play.c
4548     Fix a MacOSX specific bug which was caused by a space being inserted in
4549     the middle of a file name.
4550
4551     * configure.ac src/Makefile.am examples/Makefile.am
4552     Fix a couple of MacOSX build issues.
4553
4554 2004-02-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

4558
4559 2004-02-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4560
4561     * doc/*.html
4562     Applied patch from Frank Neumann (author of lakai) which fixes many minor
4563     typos in documentation. Thanks Frank.
4564

4568     Changed my email address throughout source and docs.
4569
4570 2004-02-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4571
4572     * src/file_io.c
4573     Make sure config.h is included before stdio.h to make sure large file
4574     support is enabled on Linux (and Solaris).
4575
4576     * tests/misc_test.c
4577     Disable update_header test on Win32. This should work but doesn't and
4578     I'm not sure why.
4579
4580     * Make.bat Win32/Makefile.msvc
4581     Updates.
4582
4583 2004-01-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4584
4585     * src/common.h
4586     Changed logindex, headindex and headend files of SF_PRIVATE from unsigned
4587     int to int to prevent weird arithmetic bugs.

4596
4597 2003-12-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4598
4599     * tests/lossy_comp_test.c tests/Makefile.am
4600     Add tests for AIFF/IMA files.
4601
4602 2003-12-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4603
4604     * src/macbinary3.c src/macos.c
4605     Two new files required for handling SD2 files.
4606
4607     * src/common.h
4608     Add prototypes for functions in above two files.
4609
4610     * src/Makefile.am
4611     Hook new files into build system.
4612
4613 2003-12-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4614
4615     * configure.ac
4616     Add checks for mmap() and getpagesize() which might be used at some time
4617     for faster file reads.
4618     Add detection of MacOSX.
4619
4620 2003-12-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4621
4622     * doc/FAQ.html
4623     Minor mods to pkg-config section.
4624
4625 2003-12-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4626
4627     * src/create_symbols_file.sh
4628     Andre Pang (also known as Ozone) pointed out that on MacOSX, all non
4629     static symbols are exported causing troubles when trying to link
4630     libsndfile with another library which has any of the same symbols.
4631     He fixed this by supplying the MacOSX linker with a file containing
4632     all the public symbols so that only they would be exported and then
4633     supplied a patch for libsndfile.
4634     This wasn't quite ideal, because I would have to maintain two (3 if
4635     you include Win32) separate files containing the exported symbols.
4636     A better solution was to create this script which can generate a
4637     Symbols file for Linux, MacoSX and any other OS that supports
4638     minimising the number of exported symbols.
4639
4640     * configure.ac src/Makefile.am
4641     Hook the new script into the build process.
4642

4644
4645     * doc/index.html
4646     Added comments about Steve Dekorte's SoundConverter scam.
4647
4648 2003-12-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4649
4650     * src/file_io.c
4651     Axel Röbel pointed out that on Mac OSX a pipe is not considered a fifo
4652     (S_ISFIFO (st.st_mode) is false) but a socket (S_ISSOCK (st.st_mode) is
4653     true). The test has therefore been changed to is S_ISREG and anything
4654     which which does not return true for S_ISREG is considered a pipe.
4655
4656 2003-11-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4657
4658     * tests/misc_test.c

4677
4678 2003-11-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4679
4680     * src/sds.c

4685
4686 2003-11-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4687
4688     * doc/FAQ.html
4689     Add Q/A about u-law encoded WAV files.
4690
4691     * Win32/*.h
4692     Updated so it compiles on Win32.
4693
4694 2003-11-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

4702
4703 2003-10-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4704
4705     * src/file_io.c
4706     Ross Bencina has contributed code to replace all of the (mostly broken)
4707     Win32 POSIX emulation calls with calls the native Win32 file I/O API.
4708     This code still needs testing but is likely to be a huge improvemnt
4709     of support for Win32. Thanks Ross.
4710
4711 2003-10-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4712
4713     * src/dwvw.c
4714     Removed filedes field from the DWVW_PRIVATE struct.
4715
4716     * src/file_io.c
4717     Change psf_fopen() so it returns psf->error instead of the file descriptor.
4718     Add new functions psf_set_stdio() and psf_set_file().
4719
4720     * src/sndfile.c
4721     Change these to work with changed psf_fopen() return value.
4722     Remove all uses of psf->filedes from sndfile, making it easier to slot native
4723     Win32 API file handling functions.
4724
4725     * src/test_file_io.c
4726     Minor changes to make it compile with new file_io.c stuff.
4727
4728 2003-10-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4729
4730     * src/gsm610.h
4731     Rename a variable from true to true_flag. As Ross Bencina points out,
4732     true is defined in the C99 header <stdbool.h>.
4733
4734     * src/file_io.c
4735     If fstat() fails, return SF_TRUE instead of -1 (Ross Bencina).
4736
4737 2003-10-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4738
4739     * src/common.h
4740     Increase the size of SF_BUFFER_LEN and SF_HEADER_LEN.
4741
4742     * src/sndfile.c

4745
4746     * examples/sndfile-info.c
4747     Increase size of BUFFER_LEN.
4748
4749 2003-09-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4750
4751     * configure.ac

4768
4769     * src/file_io.c tests/*.tpl tests/*.c
4770     More fixes for Win32/MSVC++ and MinGW. MinGW does have <unistd.h> but that
4771     file doesn't declare S_IRGRP.
4772
4773 2003-10-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4774
4775     * src/config.h.in
4776     Add comment stating that the sf_count_t typedef is determined when
4777     libsndfile is being compiled.
4778
4779     * tests/utils.tpl
4780     Modified so that utils.c gets one copy of the GPL and not two.
4781
4782
4783 2003-09-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4784
4785     * Win32/unistd.h src/sf_unistd.h
4786     Move first file to the second. This will help for Win32/MSVC++ and MinGW.
4787
4788     * Win32/Makefile.am src/Makefile.am
4789     Changed in line with above.
4790
4791     * Win32/Makefile.msvc
4792     Removed "/I Win32" which is no longer required.
4793
4794     * src/file_io.c src/test_file_io.c tests/*.tpl tests/*.c
4795     If HAVE_UNISTD_H include <unistd.h> else include <sf_unistd.h>. This should
4796     work for Win32, MinGW and other fakes Unix-like OSes.
4797
4798     * src/*.c
4799     Removed #include <unistd.h> from files which didn't need it.
4800

4851 2003-08-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4852
4853     * src/aiff.c
4854     Fixed a bug where opening a file with a non-trival header in SFM_RDWR mode
4855     would over-write part of the header. Thanks to Axel Röbel for pointing
4856     this out. Axel also provided a patch to fix this but I came up with a
4857     neater and more general solution.
4858     Return error when openning an AIFF file with data after the SSND chunk
4859     (Thanks Axel Röbel).
4860
4861     * tests/aiff_rw_test.c
4862     Improvements to test program which will later allow it to be generalised to
4863     test WAV, SVX and others as required.
4864
4865 2003-08-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

4885
4886     * configure.ac
4887     Add -Wwrite-strings warning to CFLAGS if the compiler is GCC. Thanks to
4888     Peter Miller (Aegis author) for suggesting this and supplying a patch.
4889

4900
4901     * examples/sndfile-play.c
4902     Applied a patch from Tero Pelander to allow this program to run on systems
4903     using devfs which used /dev/sound/dsp instead of /dev/dsp.
4904
4905 2003-07-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
4906
4907     * doc/new_file_type.HOWTO

4911
4912     * src/sndfile.c
4913     Fix VALIDATE_SNDFILE_AND_ASSIGN_PSF which was returning an error rather
4914     than saving it and returning zero.
4915

4917
4918     * src/file_io.c

4955     * Win32/unistd.h src/file_io.c
4956     Added implementation of S_ISFIFO macro which Win32 seems to lack and is
4957     used in src/file_io.c.
4958
4959     * tests/utils.tpl
4960     Added #include <unitstd.h> to pull in Win32/unistd.h so it compiles for
4961     Win32.
4962

4964     Added src\test_file_io.exe build target and run this as the very first
4965     test.
4966
4967     * tests/win32_test.c
4968     Add support for testing Cygwin32.

4975     file length.
4976
4977     * tests/pcm_test.tpl
4978     Add a test for lrintf() function. This was required to detect a really

4989
4990     * examples/sndfile-convert.c
4991     Modifications to improve accuracy of conversions; use double data for
4992     floating point and int for everything else.
4993
4994     * src/ima_apdcm.c
4995     Completed work on decoding IMA ADPCM encoded AIFF files. Still need to
4996     get encoding working.

5048     Fixes to allow reading from a pipe.
5049
5050 2003-05-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5051
5052     * configure.ac src/sndfile.h.in
5053     When the configure script determines the sizeof (sf_count_t), also set the
5054     value of SF_COUNT_MAX in sndfile.h.
5055
5056     * configure.ac
5057     Remove -pedantic flag from default GCC compiler flags.
5058
5059     * tests/pipe_test.c
5060     Add a pipe_read_test() before doing pipe_write_test().

5071     Fix a pair of compiler warnings.
5072
5073     * src/common.h
5074     Add new pipeoffset field to SF_PRIVATE. This will contain the current file
5075     offset when operating on a pipe.
5076
5077     * src/common.c
5078     Removed direct calls to psf_fread()/psf_fseek()/psf_fgets() etc from
5079     psf_binheader_readf and redirect them to new buffered versions
5080     header_read(), header_seek() and header_gets().
5081     Add "G" format specifier to emulate fgets() functionality with buffering.
5082     This will allow reading some file types from pipes.
5083
5084     * src/file_io.c
5085     When the file descriptor is a pipe, manintain psf->pipeoffset.
5086

5094
5095     * src/pcm.c
5096     Add clipping versions of the f2XXX_array() functions to allow option of
5097     clipping data that would otherwise overflow.
5098

5128
5129     * tests/stdin_test.c tests/stdout_test.c
5130     Removed all non-error print statements.
5131

5133     Add print statements removed from two files above.
5134
5135 2003-05-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5136
5137     * libsndfile.spec.in
5138     Fixed a coulpe of minor errors discovered by someone calling themselves
5139     Agent Smith.
5140
5141     * src/common.c src/common.h src/file_io.h
5142     Added is_pipe field to SF_PRIVATE and declaration of psf_is_pipe()
5143     function. (Axel Röbel)
5144
5145     * src/sndfile.c
5146     Fixed determination of whether the file is a pipe. (Axel Röbel)
5147
5148     * src/paf.c
5149     Force paf24 to start with undefined mode. (Axel Röbel)
5150
5151     * tests/pipe_test.c
5152     Mods to make this test work and actually do the test on RAW files. (Axel
5153     Röbel).
5154
5155 2003-05-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5156
5157     * src/sndfile.c
5158     Fixed a potential bug where psf->sf.seekable was being set to FALSE when
5159     operating on stdin or stdout but then the default initialiser was reseting
5160     it to TRUE. Thanks to Axel Röbel.
5161
5162     * src/aiff.c
5163     Fixed a bug in the header parser where it was not handling an odd length
5164     COMM chunk correctly. Thanks to Axel Röbel.
5165
5166     * src/test_file_io.c
5167     Add more tests.
5168
5169     * tests/win32_test.c
5170     New file for showing the bugs in the Win32 implementation of the POSIX API.
5171     It also runs on Linux for sanity checking.
5172
5173     * tests/Makefile.am Win32/Makefile.msvc
5174     Hook the new test program into the build system.
5175

5177
5178     * src/test_file_io.c
5179     New test program to test operation of functions defined in file_io.c. This
5180     should make supporting win32 significantly easier.
5181
5182     * src/Makefile.am
5183     Hook new test program into the build system.
5184
5185     * src/file_io.c
5186     Add compile/run time check that sizeof statbuf.st_size and sf_count_t are
5187     the same.
5188
5189     * src/common.h src/sndfile.c
5190     Added new error code and error message for new check.
5191
5192     * tests/benchmark.tpl
5193     Fix to use frames instead of samples in SF_INFO.
5194
5195 2003-05-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5196
5197     * src/file_io.c
5198     More stuffing about working around PLAIN OLD-FASHIONED **BUGS** in Win32.
5199
5200     * examples/sndfile-info.c
5201     Applied patch from Conrad Parker to add "--help" and "-h" options as
5202     well as an improved usage message.
5203
5204 2003-05-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5205
5206     * src/au.c
5207     Added embedded file support.
5208
5209     * tests/multi_file_test.c
5210     Added tests for embedded AU files.
5211     Added verbose testing mode.
5212
5213     * src/common.h src/sndfile.c
5214     Added an embedded AU specific error code and message.
5215
5216     * src/wav.c
5217     Added patch from Conrad Parker which filled in a little more information
5218     about ACIDized WAV files.
5219
5220 2003-04-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5221
5222     * src/file_io.c
5223     Fixed Win32 version of psf_fseek() which was calling psf_get_filelen()
5224     which was in turn calling psf_fseek() which in the end blew the stack.
5225     Now of course this would have been easy to find on Linux, but this blow
5226     up was happening in kernel32.dll and the fscking MSVC++ debugger couldn't
5227     figure out what call caused this (it couldn't even tell me the stack had
5228     overflowed) and was absolutley useless for this debugging exercise.
5229     On top of that, the reason I got into this mess was that windoze doesn't
5230     have a working fstat() function which can return file lengths > 2 Gig. It
5231     HAS a fscking _fstati64() but the file length value is only updated AFTER
5232     the bloody file is closed. That makes it completely useless.
5233     How the hell do people stand working on this crap excuse of an OS?
5234
5235 2003-04-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5236
5237     * Win32/unistd.h src/file_io.c
5238     Moved definitions of S_IGRP etc from file_io.c to unistd.h so that these
5239     can be used in the test programs.
5240
5241     * Win32/libsndfile.def
5242     Added sf_open_fd.
5243
5244     * Win32/sndfile.h
5245     Updated to match src/sndfile.h.in.
5246
5247     * Win32/Makefile.msvc
5248     Added dither.c and htk.c to libsndfile.dll target.
5249
5250 2003-04-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5251
5252     * src/file_io.c
5253     First attempt at getting the Win32 versions of the these functions working.
5254     They still need to be tested.
5255
5256 2003-04-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5257
5258     * src/strings.c
5259     Found and fixed a bug which was causing psf_store_string() to fail on
5260     Motorola 68k processors. Many thanks fo Joshua Haberman (Debian maintainer
5261     of libsndfile) for compiling and running debug code to help me debug the
5262     problem.
5263
5264 2003-04-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5265
5266     * src/sndfile.c src/file_io.c src/wav.c src/aiff.c
5267     Much hacking to get reading and writing of embedded files working (ie sound
5268     files at a non-zero files offset).
5269
5270     * doc/embedded_files.html
5271     First pass atempt at documenting reading/writing embedded files.
5272
5273 2003-04-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5274
5275     * doc/FAQ.html
5276     Updated answer to "Why doesn't libsndfile do interleaving/de-interleaving?"
5277
5278 2003-04-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5279
5280     * src/wav.c src/aiff.c
5281     Fix retrieving and storing of string data from files. Need to be careful
5282     about using psf->buffer for strings.
5283
5284 2003-04-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5285
5286     * src/file_io.c
5287     Fix psf_fseek() for seeks withing embedded files.
5288
5289 2003-04-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5290
5291     * src/sndfile.h.in
5292     Changed the definition of SNDFILE slightly to produce warnings when it isn't
5293     used correctly. This should have zero affect in code which uses the SNDFILE
5294     type correctly.
5295
5296     * src/sndfile.c
5297     Fixed a few compiler warnings cause by the changes to the SNDFILE type.
5298
5299 2003-04-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5300
5301     * doc/FAQ.html
5302     Added question and answer to the question "How about adding the ability
5303     to write/read sound files to/from memory buffers?".
5304
5305 2003-04-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5306
5307     * tests/write_read_test.tpl
5308     Removed un-needed enums declaring TRUE and FALSE and replaced usage of
5309     these with SF_TRUE and SF_FALSE.
5310
5311     * tests/multi_file_test.c
5312     New test program to test sf_open_fd() on files containing data other than
5313     a single sound file.
5314
5315 2003-04-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5316
5317     * src/file_io.c
5318     When creating files, set the readable by others flag. This still allows
5319     further restrictions to be enforced by use of the user's umask. Fix
5320     suggested by Eric Lyon.
5321
5322 2003-04-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5323
5324     * src/sndfile.h.in src/sndfile.c
5325     Changed sf_open_fd(). Dropped offset parameter and added a close_desc
5326     parameter. If close desc is TRUE, the file descritpor passed into the
5327     library will be closed when sf_close() is called.
5328
5329     * tests/utils.tpl
5330     Modified call to sf_open_fd() to set close_desc parameter to SF_TRUE.
5331
5332 2003-04-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5333
5334     * tests/write_read_test.tpl
5335     Add a string (using sf_set_string() function) before and after data section
5336     of all files. This will make sure that if string data can be added, it
5337     doesn't overwrite real audio data.
5338
5339 2003-04-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5340
5341     * src/sndfile.c
5342     Started work on supporting a non-zero offset parameter for sf_open_fd ().
5343
5344     * src/<file header parsers>.c
5345     Removed many uses of psf_fseek (SEEK_END) which to allow for future use of
5346     sf_open_fd() with non-zero offset.
5347     Associated refactoring.
5348
5349     * src/aiff.c
5350     Implemented functionality required to get sf_get_string() and
5351     sf_set_string() working for AIFF files.
5352
5353 2003-04-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5354
5355     * tests/utils.tpl
5356     Modified test_open_file_or_die() to alternately use sf_open() and
5357     sf_open_fd().
5358
5359     * src/svx.c
5360     Fixed a bug which occurred when openning an existing file for read/write
5361     using sf_open_fd(). In this case, the existing NAME chunk needs to be
5362     read into psf->filename.
5363     Fixed printing of sf_count_t types to logbuffer.
5364
5365 2003-03-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5366
5367     * src/sndfile.h.in
5368     Added prototype for new function sf_open_fd().
5369
5370     * src/sndfile.c
5371     Moved most of the code in sf_open() to a new function psf_open_file().
5372     Created new function sf_open_fd() which also uses psf_open_file() but
5373     does not currently support the offset parameter.
5374
5375     * doc/api.html
5376     Document sf_open_fd().
5377
5378 2003-03-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5379
5380     * src/sndfile.c
5381     Fixed a memory leak reported by Evgeny Karpov. Memory leak only occurred
5382     when an attempt was made to read and the open() call fails.
5383
5384 2003-03-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5385
5386     * tests/open_fail_test.c
5387     New test program to check for memory leaks when sf_open fails on a valid
5388     file. Currently this must be run manually under valgrid.
5389
5390     * tests/Makefile.am
5391     Hook new test program into build.
5392
5393 2003-03-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5394
5395     * Octave/sndfile_save.m Octave/sndfile_play.m
5396     Added a -mat-binary option to the octave save command to force the output
5397     to binary mode even if the user has set ascii data as the default. Found
5398     by Christopher Moore.
5399
5400 2003-02-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5401
5402     * doc/dither.html
5403     New file which will document the interface which allows the addition of
5404     audio dither when sample word sizes are being reduced.
5405
5406     * src/dither.c
5407     More work.
5408
5409 2003-02-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5410
5411     * tests/misc_test.c
5412     In update_header_test(), make HTK files a special case.

5423     Hook in htk.c
5424
5425     * tests/write_read_test.tpl tests/misc_test.c tests/Makefile.am
5426     Add tests for HTK files.
5427
5428 2003-02-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5429
5430     * src/wav.c
5431     Fixed a bug where the LIST chunk length was being written incorrectly.
5432
5433     * tests/string_test.c
5434     Added call to check_log_buffer().
5435     Minor cleanups.
5436
5437 2003-02-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5438
5439     * src/wav_w64.h
5440     Applied patch from Antoine Mathys to add extra WAV format definitions and
5441     a G72x_ADPCM_WAV_FMT struct definition.
5442
5443     * src/wav_w64.c
5444     Applied patch from Antoine Mathys which converts wav_w64_format_str() from
5445     one huge inefficient switch statement to a binary search.
5446
5447     * tests/string_test.c
5448     Dump log buffer if tests fail.
5449
5450 2003-02-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5451
5452     * tests/string_test.c
5453     David Viens supplied some modifications to this file which showed up a bug
5454     when using sf_set_string() and the sf_writef_float() functions.
5455

5460
5461     * doc/FAQ.html
5462     Added Q and A on how to detect libsndfile in configure.in (at the suggestion
5463     of Davy Durham).
5464
5465 2003-02-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5466
5467     * src/sndfile.h.in
5468     Add enums and typedefs for dither.
5469     Deprecate SFC_SET_ADD_DITHER_ON_WRITE and SFC_SET_ADD_DITHER_ON_READ, to be
5470     replaced with SFC_SET_DITHER_ON_WRITE and SFC_SET_DITHER_ON_READ which will
5471     allow different dither algorithms to be enabled.
5472     Added SFC_GET_DITHER_INFO_COUNT and SFC_GET_DITHER_INFO.
5473
5474     * src/sndfile.h.in src/Version_script.in Win32/libsndfile.def.

5499
5500 2003-02-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5501
5502     * Win32/Makefile.msvc
5503     Changes to force example binaries to be placed in the top level directory
5504     instead of the examples/ directory.
5505     Add src/strings.c and src/xi.c to the build.
5506     Add string_test to build and to tests on WAV files.
5507
5508     * doc/index.html
5509     Added XI to support matrix.
5510
5511 2003-01-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5512
5513     * src/sndfile.h.in
5514     Added prototypes for sf_get_string() and sf_set_string() and SF_STR_*
5515     enum values.
5516
5517     * src/sndfile.c
5518     Added public interface to sf_get_string() and sf_set_string().

5527     Hook new test program into build and test framework.
5528
5529 2003-01-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5530
5531     * src/common.h
5532     Added fields to SF_PRIVATE for string data needed to implement
5533     sf_get_string() and sf_set_string().
5534
5535     * src/strings.c
5536     New file for storing and retrieving strings to/from files.
5537
5538     * src/Makefile.am

5540
5541 2003-01-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5542
5543     * src/xi.c
5544     Read seems to be working so looking at write.
5545
5546     * src/sndfile.h.in
5547     Added SF_FORMAT_XI, SF_FORMAT_DPCM_8 and SF_FORMAT_DPCM_16 enum values.
5548
5549     * tests/floating_point_test.c tests/lossy_comp_test.c tests/Makefile.am
5550     Added test for 8 and 16 bit XI format files.
5551
5552 2003-01-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5553
5554     * doc/index.html
5555     Added a non-lawyer readable summary of the licensing provisions as
5556     suggested by Steve Dekorte.
5557
5558 2003-01-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5559
5560     * src/wav.c
5561     Fixed a compiler warning found by Alexander Lerch.
5562
5563 2003-01-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5564
5565     * configure.ac
5566     Fixed the multiple linking of libm.
5567
5568 2003-01-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5569
5570     * Win32/Makefile.mcvs
5571     Added comments on the correct way to set up the MSVCDir environment
5572     variable.
5573
5574     * doc/win32.html
5575     Add on how to set up the MSVCDir environment variable.
5576
5577 2003-01-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5578
5579     * examples/sndfile-play.c examples/sndfile-info.c
5580     When run on Win32 without any command line parameters print a message and
5581     then sleep for 5 seconds. This means the when somebody double clicks on
5582     these programs in explorer the user will actually see the message.
5583
5584 2003-01-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5585
5586     * tests/misc_test.c
5587     Bypass permission test if running as root because root is allowed to open
5588     a readonly file for write.
5589
5590 2003-01-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5591
5592     * Win32/Makefile.msvc
5593     Added pvf.c and xi.c source files to project.
5594
5595     * src/sndfile.h
5596     Updated for PVF files.
5597
5598 2003-01-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5599
5600     * src/sndfile.c
5601     Modified validate_sfinfo() to force samplerate, channels and sections
5602     to be >= 1.
5603     In format_from_extension() replaced calls to does_extension_match()
5604     with strcmp().
5605
5606     * src/xi.c
5607     More work.
5608
5609 2003-01-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5610
5611     * doc/Makefile.am
5612     Added octave.html which had been left out. Found by Jan Weil.
5613
5614 2003-01-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5615
5616     * src/pvf.c src/common.h src/sndfile.c
5617     Fixed error handling for PVF files.
5618
5619     * src/xi.c
5620     New file for handling Fasttracker 2 Extended Instrument files. Not working
5621     yet and included when configured with --enable-experimental.
5622
5623     * src/sndfile.c src/common.h
5624     Hooked in new file xi.c.
5625
5626 2002-12-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5627
5628     * src/rx2.c
5629     Added a patch from Marek Peteraj which sheds a little more light on the
5630     slices within an RX2 file. Still need to find out data encoding.
5631
5632 2002-12-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5633
5634     * src/wav.c
5635     Started work on decoding 'acid' and 'strc' chunks.
5636
5637 2002-12-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5638
5639     * tests/peak_check_test.c
5640     Minor cleanup.
5641
5642 2002-12-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5643
5644     * tests/write_read_test.tpl
5645     Added check to make sure no error was generated when an attempt was made to
5646     read past the end of the file.
5647
5648 2002-12-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5649
5650     * doc/lists.html
5651     Added "mailto" links for all three lists.
5652
5653     * src/pvf.c
5654     New file for Portable Voice Format files.
5655
5656     * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am
5657     Added hooks for SF_FORMAT_PVF format files.
5658
5659     * tests/write_read_test.tpl tests/std*.c
5660     Add tests for SF_FORMAT_PVF.
5661
5662     * doc/index.html
5663     Add PVF to the compatibility matrix.
5664
5665     * src/pcm.c src/alaw.c src/ulaw.c src/float32.c src/double64.c
5666     Previously, attempts to read beyond the end of a file would set psf->error
5667     to SFE_SHORT_ERROR. This behaviour diverged from the behaviour of the POSIX
5668     read() call but has now been fixed.
5669     Attempts to read beyond the end of the file will return a short read count
5670     but will not longer set any error.
5671
5672 2002-12-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5673
5674     * src/sndfile.c
5675     Add more sanity checking when opening a RAW file for read. When format is
5676     not RAW, zero out all members of the SF_INFO struct.
5677
5678     * tests/raw_test.c
5679     Add bad_raw_test() to check for above problem.
5680
5681     * tests/stdin_test.c examples/sndfile-info.c
5682     Set the format field of the SF_INFO struct to zero before calling
5683     sf_open().
5684
5685     * doc/api.html
5686     Add information about the need to set the format field of the SF_INFO struct
5687     to zero when opening non-RAW files for read.
5688
5689     * configure.ac
5690     Removed use of conversion script on Solaris. Not all Solaris versions
5691     support it.
5692
5693     * doc/lists.html
5694     New file containg details of the mailing lists.
5695
5696     * doc/index.html
5697     Add a link to the above new file.
5698
5699 2002-12-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5700
5701     * tests/dft_cmp.c
5702     Fixed a SIGFPE on Alpha caused by a log10 (0.0). Thanks to Joshua Haberman
5703     for providing the gdb traceback.
5704
5705 2002-11-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5706
5707     * src/wav.c
5708     Added more capabilities to 'smpl' chunk parser.
5709
5710     * src/sndfile.c
5711     Fixed some (not all) possible problems found with Flawfinder.
5712
5713 2002-11-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5714
5715     * src/sndfile.c
5716     Fixed a bug in sf_seek(). This bug could only occur when an attempt was
5717     made to read beyond the end and then sf_seek() was called with a whence
5718     parameter of SEEK_CUR.
5719
5720     * src/file_io.c
5721     Win32's _fstati64() does not work, it returns BS. Re-implemented
5722     psf_get_filelen() in terms of psf_fseek().
5723
5724     * tests/write_read_test.tpl
5725     Add a test to detect above bug.
5726
5727     * src/float_cast.h
5728     Modification to prevent compiler warnings on Mac OS X.
5729
5730     * src/file_io.c
5731     Fixes for windows (what a f**ked OS).
5732
5733 2002-11-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5734
5735     * configure.ac
5736     Disable use of native lrint()/lrintf() on Mac OSX. These functions exist on
5737     Mac OSX 10.2 but not on 10.1. Forcing the use of the versions in
5738     src/float_cast.h means that a library compiled on 10.2 will still work on
5739     10.1.
5740
5741 2002-11-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5742
5743     * configure.in configure.ac
5744     Renamed configure.in to configure.ac as expected by later versions of
5745     autoconf.
5746     Slight hacking of configure.ac to work with version 2.54 of autoconf.
5747     Changed to using -dumpversion instead of --version for determining GCC
5748     version numer as suggested by Anand Kumria.
5749
5750     * src/G72x/Makefile.am
5751     Slight hacking required for operation with automake 1.6.3.
5752
5753 2002-11-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5754
5755     * src/common.c
5756     In psf_binheader_readf() changed type parameter type "b" type from size_t
5757     to int to prevent errors on IA64 CPU where sizeof (size_t) != sizeof (int).
5758     Thanks to Enrique Robledo Arnuncio for debugging this.
5759
5760 2002-11-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5761
5762     * test/command_test.tpl
5763     Changed test value so test would pass on Solaris.
5764
5765     * src/Version_script.in
5766     Modified version numbering so that later versions of 1.0.X can replace
5767     earlier versions without recompilation.
5768
5769     * src/vox_adpcm.c
5770     Fixed bug causing short reads.
5771
5772 2002-11-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5773
5774     * test/floating_point_test.c
5775     Code cleanup using functions from util.c.
5776     Add test for IEEE replacement floats and doubles.
5777
5778 2002-11-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5779
5780     * src/wav.c
5781     Fixed a possible divide by zero error when read the 'smpl' chunk. Thanks to
5782     Serg Repalov for the example file.
5783
5784     * tests/pcm_test.tpl
5785     Used sf_command (SFC_TEST_IEEE_FLOAT_REPLACE) to test IEEE replacement code.
5786     Clean up pcm_double_test().
5787
5788     * src/float32.c src/double64.c
5789     Force use of IEEE replacement code using psf->ieee_replace is TRUE,
5790     Print message to log_buffer as well.
5791     Rename all broken_read_* and broken_write* functions to replace_read_* and
5792     replace_write_*.
5793
5794     * tests/util.tpl
5795     Added string_in_log_buffer().
5796
5797     * tests/pcm_test.tpl
5798     Use string_in_log_buffer() to ensure that IEEE replacement code has been
5799     used.
5800
5801     * configure.in
5802     Removed --enable-force-broken-float option. IEEE replacement code is now
5803     always tested.
5804
5805 2002-10-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
5806
5807     * src/double64.c
5808     Implement code for read/writing IEEE doubles on platforms where the native

5810
5811     * src/float32.c src/common.h
5812     Remove float32_read() and float32_write(). Replace with float32_le_read(),
5813     float32_be_read(), float32_le_write() and float32_be_write() to match stuff
5814     in src/double64.c.
5815
5816     * src/common.c
5817     Fix all usage of float32_write().

5829
5830     * tests/pcm_test.tpl
5831     Fixed a problem when testing with --enable-force-broken-float. The test was
5832     generating a value of negative zero and the broken float code is not able
5833     to write negative zero. Removing the negative zero fixed the test.
5834
5835 2002-10-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

5854     are no longer needed.
5855
5856     * tests/misc_test.c
5857     Added test to make sure the correct error message is returned with an
5858     existing read-only file is openned for write.
5859

5878     its functionality to detect headerless VOX files.
5879
5880     * src/raw.c
5881     Added hooks for SF_FORMAT_VOX_ADPCM.
5882

5938     Renamed the first to the latter.
5939
5940     * examples/Makefile.am
5941     Added sndfile-convert to the bin_PROGRAMS, so it is installed when the lib
5942     is installed.
5943     Removed old programs wav32_aiff24 and sndfile2oct.
5944
5945     * man/sndfile-convert.1

5994     * src/wav.c
5995     Added handling of brain-damaged and broken Cooledit "32 bit 24.0 float
5996     type 1" files. These files are marked as being 24 bit WAVE_FORMAT_PCM with
5997     a block alignment of 4 times the numbers of channels but are in fact 32 bit
5998     floating point.
5999

6252     * src/Makefile.am
6253     Added src/interleave.c to build.
6254
6255 2002-09-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6256
6257     * src/double64.c src/common.h
6258     Added double64_be_read(), double64_le_read(), double64_be_write() and
6259     double64_le_write() which replace double64_read() and double64_write().
6260
6261     * src/common.c
6262     Cleanup of psf_binheader_readf() and add ability to read big and little
6263     endian doubles (required by mat4.c and mat5.c).
6264     Add ability for psf_binheader_writef() to write doubles to sound file
6265     headers.
6266
6267 2002-09-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6268
6269     * src/mat5.c
6270     New file for reading Matlab (tm) version 5 data files. This is also the
6271     native binary file format for version 2.1.X of GNU Octave which will be
6272     used for testing.
6273     Not complete yet.
6274
6275     * src/mat4.c
6276     New file for reading Matlab (tm) version 4.2 data files. This is also the
6277     native binary file format for version 2.0.X of GNU Octave which will be
6278     used for testing.
6279     Not complete yet.
6280
6281     * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am
6282     Mods to add Matlab files.
6283
6284     * src/common.[ch]
6285     Added readf_endian field to SF_PRIVATE struct allowing endianness to
6286     remembered across calls to sf_binheader_readf().
6287     Fixed bug in width_specifier behaviour for printing hex values.
6288
6289 2002-08-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6290
6291     * src/file_io.c
6292     Check return value of close() call in psf_fclose().
6293
6294 2002-08-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6295
6296     * src/ms_adpcm.c
6297     Commented out some code where 0x10000 was being subtracted from a short
6298     and the result assigned to a short again. Andrew Zaja found this.
6299
6300 2002-08-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6301
6302     * doc/command.html
6303     Fixed typo found by Tommi Ilmonen.
6304
6305     * src/ima_adpcm.c
6306     Changed type of diff from short to int to prevent errors which can occur
6307     during very rare circumstances. Thanks to FUWAFUWA.
6308
6309 2002-08-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6310
6311     * tests/floating_point_test.c
6312     Disable testing on machines without lrintf().
6313
6314     * Win32/Makefile.msvc
6315     Added dwd.c and wve.c to build.
6316
6317     * configure.in
6318     Bumped version to 1.0.0.
6319
6320 2002-08-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6321
6322     * src/file_io.c
6323     Add a #include for Mac OS 9. Thanks to Stephane Letz.
6324
6325     * src/wav.c
6326     Changed an snprintf to LSF_SNPRINTF.
6327
6328     * doc/Makefile.am
6329     Added version-1.html.
6330
6331 2002-08-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6332
6333     * configure.in
6334     Bumped version to 1.0.rc6.
6335
6336     * src/*.c
6337     Modified scaling of normalised floats and doubles to integers. Until now
6338     this has been done by multiplying by 0x8000 for short output, 0x80000000
6339     for 32 bit ints and so on. Unfortunately this can cause an overflow and
6340     wrap around in the target value. All thes values have therefore been
6341     reduced to 0x7FFF, 0x7FFFFFFF and so on. The conversion from ints to
6342     normalised floats and doubles remains unchanged. This does mean that for
6343     repeated conversions normalised float -> pcm16 -> normalised float would
6344     result in a decrease in amplitude of 0x7FFF/0x8000 on every round trip.
6345     This is undesirable but less undesireable than the wrap around I am trying
6346     to avoid.
6347
6348     * tests/floating_point_test.c
6349     Removed file hash checking because new float scaling procedure introduced
6350     above prevented the ability to crate a has on both x86 and PowerPC systems.
6351
6352 2002-08-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6353
6354     * src/txw.c
6355     Completed reading of TXW files. Seek doesn't work yet.
6356
6357     * src/file_io.c
6358     Added a MacOS 9 replacement for ftruncate().
6359
6360     * MacOS/sndfile.h
6361     Added MacOS 9 header file. This should be copied into src/ to compile
6362     libsndfile for MacOS9.
6363
6364 2002-08-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6365
6366     * src/sndfile.c
6367     Fixed commands SF_SET_NORM_DOUBLE and SFC_SET_NORM_FLOAT to return their
6368     values after being set. Reported by Jussi Laako.
6369
6370     * configure.in
6371     If autogen is not found, touch all .c and .h files in tests/.
6372
6373     * src/common.c
6374     Added format width specifier to psf_log_printf() for %u, %d, %D and %X.
6375
6376     * src/dwd.c
6377     Completed implementation of read only access to these files.
6378
6379     * src/common.h src/*.c src/pcm.c
6380     Removed redundant field chars from SF_PRIVATE struct and modified
6381     pcm_init() to do without it.
6382
6383 2002-08-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6384
6385     * src/wve.c
6386     New file implementing read of Psion Alaw files. This will be a read only
6387     format. Implementation complete.
6388
6389     * src/dwd/c
6390     Started implementation of DiamondWare Digitized files. Also read only, not
6391     complete.
6392
6393     * src/wav.c
6394     Add parsing of 'smpl' chunk.
6395
6396     * src/paf.c
6397     Fixed reading on un-normalized doubles and floats from 24 bit PAF files.
6398     This brings it into line with the reading of 8 bit files into
6399     un-normalized doubles which returns values in the range [-128, 127].
6400
6401     * src/common.c
6402     Modified psf_log_printf() to accept the %% conversion specifier to allow
6403     printing of a single '%'.
6404
6405     * src/sds.c
6406     Read only of 16 bit samples is working. Need to build a test harness for
6407     this and other read only formats.
6408
6409 2002-08-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6410
6411     * configure.in
6412     Added --enable-experimental configure option.
6413     Removed pkg-config message at the end of the configure process.
6414
6415     * src/sds.c src/txw.c src/rx2.c src/sd2.c
6416     Moved all the code in these files inside #if ENABLE_EXPERIMENTAL_CODE
6417     blocks and added new *_open() function for the case where experimental is
6418     not enabled. These new functions just return SFE_UNIMPLMENTED.
6419
6420     * Win32/sndfile.h src/sndfile.h.in src/common.h
6421     Removed un-necessary #pragma pack commands.
6422
6423     * src/file_io.c
6424     Implemented psf_ftruncate() and much other hacking for Win32.
6425
6426     * Win32/Makefile.msvc
6427     Updated.
6428
6429     * doc/win32.html
6430     Updated to include the copying of the sndfile.h file from the Win32/
6431     directory to the src/ directory.
6432
6433     * Make.bat
6434     Batch file to make compiling on Wi32 a little easier. Implements "make" and
6435     "make check".
6436
6437 2002-08-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6438
6439     * src/file_io.c
6440     Add place holder for ftruncate() on Win32 which doesn't have ftruncate().
6441     This will need to be fixed later.
6442
6443     * src/sndfile.h.in
6444     New file (copy of sndfile.h) with sets up @TYPEOF_SF_COUNT_T@ which will be
6445     replaced by the correct type during configure.
6446
6447     * configure.in
6448     Modified to find a good type for TYPEOF_SF_COUNT_T.
6449
6450     * src/aiff.c
6451     Fixed a bug when reading malformed headers.
6452
6453     * src/common.c
6454     Set read values to zero before performing read.
6455
6456 2002-08-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6457
6458     * doc/command.html
6459     Fixed some HTML tags which were not allowing jumps to links within the
6460     page.
6461
6462     * src/sds.c
6463     Massive hacking on this.
6464

6467
6468 2002-08-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6469
6470     * doc/index.html
6471     Added beginning of a capabilities list beyond simple file formats which
6472     can be read/written.
6473
6474     * src/aiff.c
6475     Added parsing of INST and MARK chunks of AIFF files. At the moment this
6476     data is simply recorded in the log buffer. Later it will be possible to
6477     read this data from an application using sf_command().
6478
6479     * src/wav.c
6480     Added parsing of 'cue ' chunk which contains loop information in WAV files.
6481
6482     * exampes/sndfile-info.c
6483     Changed reporting of Samples to Frames.
6484
6485     * src/wav.c src/w64.c src/aiff.c src/wav_w64.h
6486     Moved from a samples to a frames nomenclature to avoid confusion.
6487

6493
6494     * src/Makefile.am src/sndfile.c src/common.[ch]
6495     Added hooks for sds.c.
6496
6497     * examples/sndfile-info.c
6498     Changed from using sf_perror() to using sf_error_str().
6499
6500 2002-08-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6501
6502     * doc/api.html
6503     Added explanation of mode parameter for sf_open().
6504     Added explanation of usage of SFM_* values in sf_seek().
6505
6506     * src/sndfile.[ch] src/command.c src/file_io.c src/common.h
6507     Implemented SFC_FILE_TRUNCATE to allow a file to be truncated. File
6508     truncation was suggested by James McCartney.
6509
6510     * src/command.html
6511     Documented SFC_FILE_TRUNCATE.
6512
6513     * tests/command_test.c
6514     Add tests for SFC_FILE_TRUNCATE.
6515
6516     * src/sndfile.c
6517     Added a thrid parameter to the VALIDATE_SNDFILE_AND_ASSIGN_PSF macro to
6518     make resetting the error number optional. All uses of the macro other than
6519     in error reporting functions were changed to reset the error number.
6520
6521     * src/pcm.c
6522     Fixed a bug were sf_read_* was logging an SFE_SHORT_READ even when no error
6523     occurred.
6524
6525     * tests/write_read_test.tpl
6526     Added tests of internal error state.
6527
6528 2002-08-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6529
6530     * src/GSM610/private.h src/GSM610/*.c src/GSM610/Makefile.am
6531     Renamed private.h to gsm610_priv.h to prevent clash with other headers
6532     named private.h in other directories. (Probably only a problem on MacOS 9).
6533
6534     * src/G72x/private.h src/G72x/*.c src/G72x/Makefile.am
6535     Renamed private.h to g72x_priv.h to prevent clash with other headers
6536     named private.h in other directories. (Probably only a problem on MacOS 9).
6537
6538     * MacOS/config.h
6539     Changed values of HAVE_LRINT and HAVE_LRINTF to force use of code in
6540     float_cash.h.
6541
6542     * src/sndfile.h
6543     Changes the name of samples field of the SF_INFO to frames. The old name
6544     had caused too much confusion and it simply had to be changed. There will
6545     be at least one more pre-release.
6546
6547 2002-08-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6548
6549     * doc/index.html
6550     Updated formats matrix to include RAW (header-less) GSM 6.10.
6551     Fix specificaltion of table and spelling mistakes.
6552
6553     * src/sndfile.c src/command.c

6575     Fix file hash check on systems without lrint/lrintf.
6576
6577     * tests/dft_cmp.c
6578     Limit SNR to less than -500.0dB.
6579
6580     * examples/sndfile2oct.c
6581     Fixed compiler warnings.
6582
6583     * doc/api.html
6584     Fixed error where last parameter of sf_error_str() was sf_count_t instead
6585     of size_t.
6586
6587 2002-08-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6588
6589     * doc/FAQ.html
6590     Why doesn't libsndfile do interleaving/de-interleaving.
6591
6592     * tests/pcm_test.tpl
6593     On Win32 do not perform hash check on files containing doubles.
6594
6595 2002-08-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6596
6597     * src/common.h
6598     Defined SF_COUNT_MAX_POSITIVE() macro, a portable way of setting variables
6599     of type sf_count_t to their maximum positive value.
6600
6601     * src/dwvw.c src/w64.c
6602     Used SF_COUNT_MAX_POSITIVE().
6603
6604 2002-07-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6605
6606     * src/paf.c
6607     Fixed bug in reading/writing of 24 bit PCM PAF files on big endian systems.
6608
6609     * tests/floating_point_tests.c
6610     Fixed hash values for 24 bit PCM PAF files.
6611     Disabled file has check if lrintf() function is not available and added
6612     warning.
6613     Decreased level of signal from a peak of 1.0 to a value of 0.95 to prevent
6614     problems on platforms without lrintf() ie Solaris.
6615
6616 2002-07-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6617
6618     * src/wav.c
6619     Fixed a problem with two different kinds of mal-formed WAV file header. The
6620     first had the 'fact' chunk before the 'fmt ' chunk, the other had an
6621     incomplete 'INFO' chunk at the end of the file.
6622
6623     * src/w64.c
6624     Added fix to allow differentiation between W64 files and ACID files.
6625
6626     * src/au_g72x.c src/common.h src/sndfile.c
6627     Added error for G72x encoded files with more than one channel.
6628
6629     * tests/pcm_test.tpl tests/utils.tpl
6630     Moved function check_file_hash_or_die() to utils.tpl. Function was then
6631     modified to calculate the has of the whole file.
6632
6633     * src/wav.c
6634     Fixed problem writing the 'fact' chunk on big endian systems.
6635
6636     * tests/sfconvert.c
6637     Fixed bug where .paf files were being written as Sphere NIST.
6638
6639 2002-07-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6640
6641     * src/voc.c
6642     Fix for reading headers generated using SFC_UPDATE_HEADER_NOW.

6646
6647 2002-07-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6648
6649     * man/sndfile-info.1 man/sndfile-play.1
6650     Added manpages supplied by Joshua Haberman the Debian maintainer for
6651     libsndfile. Additional tweaks by me.
6652
6653     * configure.in man/Makefile.am
6654     Hooked manpages into autoconf/automake system.
6655
6656     * src/sndfile.c
6657     Added hooks for SFC_SET_UPDATE_HEADER_AUTO.
6658
6659     * tests/update_header_test.c
6660     Improved rigor of testing.
6661
6662     * src/*.c
6663     Fixed problem with *_write_header() functions.
6664
6665 2002-07-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6666
6667     * doc/*.html
6668     Updates to documentation to fix problems found by wdg-html-validator.
6669
6670     * src/common.h src/command.c
6671     Added normalize parameter to calls to psf_calc_signal_max() and
6672     psf_calc_max_all_channels().
6673
6674     * src/sndfile.c
6675     Added handling for commands SFC_CALC_NORM_SIGNAL_MAX and
6676     SFC_CALC_NORM_MAX_ALL_CHANNELS.
6677
6678     * doc/command.html
6679     Added entry for SFC_CALC_NORM_SIGNAL_MAX and SFC_CALC_NORM_MAX_ALL_CHANNELS.
6680
6681 2002-07-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6682
6683     * examples/sndfile-play.c Win32/Makefile.msvc
6684     Get sndfile-play program working on Win32. The Win32 PCM sample I/O API
6685     sucks. The sndfile-play program now works on Linux, MacOSX, Solaris and
6686     Win32.

6738     * src/sndfile.h src/common.h
6739     Moved some yet-to-be-implelmented values for SF_FORMAT_* from the public
6740     header file sndfile.h to the private header file common.h to avoid
6741     confusion about the actual capabilities of libsndfile.
6742

6759
6760     * tests/command_test.c
6761     For SFC_SET_NORM_* tests, change the file format from SF_FORMAT_WAV to
6762     SF_FORMAT_RAW.
6763
6764     * src/sndfile.c
6765     Added sf_command(SFC_TEST_ADD_TRAILING_DATA) to allow testing of reading

6767
6768     * src/common.h
6769     Add test commands SFC_TEST_WAV_ADD_INFO_CHUNK and
6770     SFC_TEST_AIFF_ADD_INST_CHUNK. When these commands are working, they will be
6771     moved to src/sndfile.h
6772
6773     * src/aiff.c src/wav.c
6774     Begin implementation of XXXX_command() hook for sf_command().
6775
6776     * tests/write_read_test.tpl
6777     Added sf_command (SFC_TEST_ADD_TRAILING_DATA) to ensure above new code was

6784     files.
6785
6786     * tests/write_read_test.tpl tests/pcm_test.tpl
6787     Fixed some problems in the test suite discovered by using Valgrind.
6788
6789 2002-07-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6790
6791     * tests/utils.[ch] tests/*.c
6792     Renamed check_log_buffer() to check_log_buffer_or_die().
6793
6794     * src/sndfile.c
6795     SFC_UPDATE_HEADER_NOW and SFC_SETUPDATE_HEADER_AUTO almost finished. Works
6796     for all file formats other than VOC.
6797
6798 2002-07-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6799
6800     * src/sndfile.[ch] src/common.h
6801     Started adding functionality to allow the file header to be updated before
6802     the file is closed on files open for SFM_WRITE. This was requested by
6803     Maurizio Umberto Puxeddu who is using libsndfile for file I/O in iCSound.
6804
6805     * tests/update_header_test.c
6806     New test program to test that the above functionality is working correctly.
6807
6808     * tests/peak_chunk_test.c tests/floating_point_test.c

6810
6811 2002-07-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6812
6813     * src/sfendian.[ch]
6814     Changed length count parameters for all endswap_XXX() functions from
6815     sf_count_t (which can be 64 bit even on 32 bit architectures) to int. These
6816     functions are only called frin inside the library, are always called with
6817     integer parameters and doing the actual calculation on 64 bit values is
6818     slow in comparision to doing it on ints.
6819
6820     * examples/sndfile-play.c
6821     More playback hacking for Win32.
6822
6823 2002-07-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6824
6825     * src/common.c
6826     In psf_log_printf(), changed %D format conversion specifier to %M (marker) and
6827     added %D specifier for printing the sf_count_t type.
6828
6829     * src/*.c
6830     Changed all usage of psf_log_printf() with %D format conversion specifiers
6831     to use %M conversion instead.
6832
6833     * tests/pcm_test.tpl tests/pcm_test.def
6834     New files to autogen pcm_test.c.
6835
6836     * src/pcm.c
6837     Fixed bug in scaling floats and doubles to 24 bit PCM and vice versa.
6838
6839 2002-07-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6840
6841     * configure.in
6842     Fix setup of $ac_cv_sys_largefile_CFLAGS so that sndfile.pc gets valid
6843     values for CFLAGS.
6844
6845     * examples/sndfile-play.c
6846     Start adding playback support for Win32.
6847
6848 2002-07-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6849
6850     * src/*.c
6851     Worked to removed compiler warnings.
6852     Extensive refactoring.
6853
6854     * src/common.[ch]
6855     Added function psf_memset() which works like the standard C function memset
6856     but takes and sf_count_t as the length parameter.
6857
6858     * src/sndfile.c
6859     Replaced calls to memset(0 with calls to psf_memset() as required.
6860
6861 2002-07-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6862
6863     * src/sndfile.c
6864     Added "libsndfile : " to the start of all error messages. This was suggested
6865     by Conrad Parker author of Sweep ( http://sweep.sourceforge.net/ ).
6866
6867     * src/sfendian.[ch]
6868     Added endswap_XXXX_copy() functions.
6869
6870     * src/pcm.c src/float32.c src/double64.c
6871     Use endswap_XXXX_copy() functions and removed dead code.
6872     Cleanups and optimisations.
6873
6874 2002-07-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6875
6876     * src/sndfile.c src/sndfile.h
6877     Gave values to all the SFC_* enum values to allow better control of the
6878     interface as commands are added and removed.
6879     Added new command SFC_SET_ADD_PEAK_CHUNK.
6880
6881     * src/wav.c src/aiff.c
6882     Modified wav_write_header and aiff_write_header to make addition of a PEAK
6883     chunk optional, even on floating point files.
6884
6885     * tests/benchmark.tpl
6886     Added call to sf_command(SFC_SET_ADD_PEAK_CHUNK) to turn off addition of a
6887     PEAK chunk for the benchmark where we are trying to miximize speed.
6888
6889     * src.pcm.c
6890     Changed tribyte typedef to something more sensible.
6891     Further conversion speed ups.
6892
6893 2002-07-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6894
6895     * src/command.c
6896     In major_formats rename "Sphere NIST" to "NIST Sphere".
6897
6898     * src/common.c src/sfendian.c
6899     Moved all endswap_XXX_array() functions to sfendian.c. These functions will
6900     be tweaked to provide maximum performance. Since maximum performance on one
6901     platform does not guarantee maximum performance on another, a small set of
6902     functions will be written and the optimal one chosen at compile time.
6903
6904     * src/common.h src/sfendian.h
6905     Declarations of all endswap_XXX_array() functions moved to sfendian.h.
6906
6907     * src/Makefile.am
6908     Add sfendian.c to build targets.
6909
6910 2002-07-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6911
6912     * src/pcm.c src/sfendian.h
6913     Re-coded PCM encoders and decoders to match or better the speed of
6914     libsndfile version 0.0.28.
6915
6916 2002-06-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6917
6918     * src/wav.c
6919     Add checking for WAVPACK data in standard PCM WAV file. Return error if
6920     found. This WAVPACK is *WAY* broken. It uses the same PCM WAV file header
6921     and then stores non-PCM data.
6922
6923     * tests/benchmark.tpl
6924     Added more tests.
6925
6926 2002-06-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6927
6928     * tests/benchmark.tpl
6929     Added conditional definition of M_PI.
6930     For Win32, set WRITE_PERMS to 0777.
6931
6932     * Win32/Makefile.msvc
6933     Added target to make generate program on Win32.
6934
6935     * src/samplitude.c
6936     Removed handler for Samplitude RAP file format. This file type seems rarer
6937     than hens teeth and is completely undocumented.
6938
6939     * src/common.h src/sndfile.c src/Makefile.am Win32/Makefile.msvc
6940     Removed references to sampltiude RAP format.
6941
6942     * tests/benchmark.tpl
6943     Benchmark program now prints the libsndfile version number when run. This
6944     program was also backported to version 0 to compare results. Version
6945     1.0.0rc2 is faster than version 0.0.28 on most conversions but slower on
6946     some. The slow ones need to be fixed before final release.
6947
6948 2002-06-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6949
6950     * tests/benchmark.def tests/benchmark.tpl
6951     New files which generate tests/benchmark.c using Autogen. Added int ->
6952     SF_FORMAT_PCM_24 test.
6953
6954     * tests/benchmark.c
6955     Now and Autogen output file.
6956
6957     * tests/Makefile.am
6958     Updated for above changes.
6959
6960 2002-06-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6961
6962     * tests/benchmark.c
6963     Basic benchmark program complete. Need to convert it to Autogen.
6964
6965     * Win32/Makefile.msvc
6966     Added benchmark.exe target.
6967
6968 2002-06-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6969
6970     * examples/generate.c
6971     New program to generate a number of different output file formats from a
6972     single input file. This allows testing of the created files.
6973
6974     * tests/benchmark.c
6975     New test program to benchmark libsndfile. Nowhere near complete yet.
6976
6977     * examples/Makefile.am tests/Makefile.am
6978     New make rules for the two new programs.
6979
6980 2002-06-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
6981
6982     * Win32/libsndfile.def
6983     Removed definition for sf_signal_max().

6993
6994     * configure.in
6995     Bumped version to 1.0.0rc2.
6996
6997     * src/sf_command.h src/Makefile.am
6998     Removed the header file as it was no longer being used. Thanks to Anand
6999     Kunria for spotting this.
7000
7001     * doc/index.html
7002     A number of documentation bugs were fixed. Thanks to Anand Kumria.
7003

7005
7006     * src/common.h
7007     Test for Win32 before testing SIZEOF_OFF_T so that it works correctly
7008     on Win32..
7009
7010     * src/file_io.c
7011     Win32 fixes to ensure O_BINARY is used for file open.
7012
7013     * doc/win32.html
7014     New file documenting the building libsndfile on Win32.
7015

7031
7032     * src/format.c src/command.c
7033     Renamed format.c to command.c which will now include code for sf_command()
7034     calls to perform operations other than format commands.
7035
7036     * src/sndfile.c src/sndfile.h
7037     Removed function sf_get_signal_max() which is replaced by commands passed
7038     to sf_command().
7039
7040     * src/command.c
7041     Implement commands SFC_CALC_SIGNAL_MAX.
7042
7043     * doc/command.html
7044     Documented SFC_CALC_SIGNAL_MAX.
7045
7046 2002-06-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7047
7048     * examples/sndfile-play.c
7049     Mods to make sndfile-play work on Solaris. The program sndfile-play now
7050     runs on Linux, MaxOSX and Solaris. Win32 to come.
7051
7052     * src/format.c
7053     Added SF_FORMAT_DWVW_* to subtype_formats array.
7054

7056     Added support for 8 bit NIST Sphere files. Example file supplied by Anand
7057     Kumria.
7058
7059 2002-06-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7060
7061     * examples/sndfile-info.c
7062     Tidy up of output format.
7063
7064     * examnples/sndfile-play.c
7065     Mods to make sndfile-play work on MacOSX using Apple's CoreAudio API.
7066
7067     * configure.in
7068     Add new variables OS_SPECIFIC_INCLUDES and OS_SPECIFIC_LINKS which were
7069     required to supply extra include paths and link parameters to get
7070     sndfile-play working on MacOSX.
7071
7072     * examples/Makefile.am
7073     Use OS_SPOECIFIC_INCLUDES and OS_SPECIFIC_LINKS to build commands for
7074     sndfile-play.
7075

7098
7099     * Win32/unistd.h src/file_io.c
7100     Moved contents of first file into the second file (enclosed in #ifdef).
7101     Win32/unistd.h is now an empty file but still must be there for libsndfile
7102     to compile on Win32.
7103
7104     * src/sd2.c, src/sndfile.c:
7105     Fixes for Sound Designer II files on big endian systems.

7114
7115     * src/sndfile.c
7116     Code clean up in sf_open ().
7117
7118     * Win32/Makefile.msvc

7120     together in a new improved form.
7121
7122     * src/file_io.c
7123     Fixes for Win32; _lseeki64() returns an invalid argument for calls like
7124     _lseeki64(fd, 0, SEEK_CUR) so need to use _telli64 (fd) instead.
7125
7126     * src/common.h src/sndfile.c src/wav.c src/aiff.c
7127     Added SFE_LOG_OVERRUN error.
7128     Added termination for potential infinite loop when parsing file headers.
7129
7130     * src/wav.c src/w64.c
7131     Fixed bug casuing incorrect header generation when opening file read/write.
7132
7133 2002-06-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7134
7135     * doc/api.html
7136     Improved the documentation to make it clearer that the file read method
7137     and the underlying file format are completely disconnected. Suggested
7138     by Josh Green.
7139
7140     * doc/command.html
7141     Started correcting docs to take into account changes made to the
7142     operations of the sf_command () function. Not complete yet.
7143
7144     * src/sndfile.c
7145     Reverted some changes which had broken the partially working SDII header
7146     parsing. Now have access to an iBook with OS X so reading and writing SDII
7147     files on all platforms should be a reality in the near future. On Mac this
7148     will involve reading the resource fork via the standard MacOS API. To move
7149     a file from Mac to another OS, the resource and data forks will need to be
7150     combined before transfer. The combined file will be read on both Mac and
7151     other OSes like any other file.
7152
7153 2002-06-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7154
7155     * ltmain.sh
7156     Applied a patch from http://fink.sourceforge.net/doc/porting/libtool.php
7157     which allows libsndfile to compile on MacOSX 10.1. This patch should not
7158     interfere with compiling on other OSes.
7159
7160     * src/GSM610/private.h
7161     Changes to fix compile problems on MacOSX (see src/GSM610/ChangeLog).
7162
7163     * src/float_cast.h
7164     Added MacOSX replacements for lrint() and lrintf().
7165
7166 2002-06-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7167
7168     * src/sndfile.c
7169     Replaced the code to print the filename to the log buffer when a file is
7170     opened. This code seems to have been left out during the merge of
7171     sf_open_read() and sf_open_write() to make a single  functions sf_open().
7172
7173 2002-06-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7174
7175     * src/wav.c
7176     Fixed a bug where the WAV header parser was going into an infinite loop
7177     on a badly formed LIST chunk. File supplied by David Viens.
7178
7179 2002-05-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7180
7181     * configure.in
7182     Added a message at the end of the configuration process to warn about the
7183     need for the use of pkg-config when linking programs against version 1 of
7184     libsndfile.
7185
7186     * doc/pkg-config.html
7187     New documentation file containing details of how to use pkg-config to
7188     retrieve settings for CFLAGS and library locations for linking files
7189     against version 1 of libsndfile.
7190
7191 2002-05-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7192
7193     * src/wav.c
7194     Fixed minor bug in handling of so-called ACIDized WAV files.
7195
7196 2002-05-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7197
7198     * Win32/libsndfile.def Win32/Makefile.msvc
7199     Two new files contributed by Michael Fink (from the winLAME project)
7200     which allows libsndfile to be built on windows in a MSDOS box by doing
7201     "nmake -f Makefile.msvc". Way cool!
7202
7203 2002-05-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7204
7205     * configure.in
7206     MacOSX is SSSOOOOOOO screwed up!!! I can't believe how hard it is to
7207     generate a tarball which will configure and compile on that platform.
7208     Joined the libtool mailing list to try and get some answers.
7209
7210 2002-05-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7211
7212     * configure.in
7213     Changed to autoconf version 2.50. MacOSX uses autoconf version 2.53 which
7214     is incompatible with with version 2.13 which had been using until now.
7215     The AC_SYS_LARGE_FILE macro distributed withe autoconf 2.50 is missing a
7216     few features so AC_SYS_EXTRA_LARGE file was defined to replace it.
7217
7218     * configure.in
7219     Changed to automake version 1.5 to try and make a tarball which will
7220     work on MacOSX.
7221
7222 2002-05-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7223
7224     * src/wav_gsm610.c
7225     Changed name to gsm610.c. Added reading/writing of headerless files.
7226
7227     * src/sndfile.c src/raw.c
7228     Added ability to read/write headerless (SF_FORMAT_RAW) GSM 6.10 files.
7229
7230 2002-05-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7231
7232     * tests/lossy_comp_test.c
7233     Clean up in preparation for Autogen-ing this file.
7234
7235     * src/GSM610/*.[ch]
7236     Code cleanup and prepartion forgetting file seek working. Details in
7237     src/GSM610/ChangeLog.
7238
7239     * sndfile.pc.in
7240     Testing complete. Is sndfile.m4 still needed?
7241
7242 2002-05-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7243
7244     * tests/write_read_test.tpl tests/rdwr_test.tpl
7245     Merged tests from these two programs into write_read_test.tpl and deleted
7246     rdwr_test.tpl.
7247
7248 2002-05-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7249
7250     * src/w64.c src/svx.c src/paf.c
7251     Fixed bugs in read/write mode.
7252
7253 2002-05-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7254
7255     * examples/Makefile.am
7256     Renamed sfplay.c to sndfile-play.c and sndfile_info.c to sndfile-info.c for
7257     consistency when these programs become part of the Debian package
7258     sndfile-programs.
7259
7260     * sndfile.pc.in
7261     New file to replace sndfile-config.in. Libsndfile now uses the pkg-config
7262     model for providing installation parameters to dependant programs.
7263
7264     * src/sndfile.c
7265     Cleanup of code in sf_open().
7266
7267 2002-05-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7268
7269     * tests/utils.tpl tests/write_read_test.tpl
7270     More conversion to Autogen fixes and enchancements.
7271
7272     * src/*.c
7273     Read/write mode is now working for 16, 24 and 32 bit PCM as well as 32
7274     bit float and 64 bit double data. More tests still required.
7275
7276     * src/Makefile.am
7277     Added DISTCLEANFILES target to remove config.status and config.last.
7278
7279     * Win32/Makefile.am MacOS/Makefile.am
7280     Added DISTCLEANFILES target to remove Makefile.
7281
7282 2002-05-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7283
7284     * src/*.[ch] tests/rdwr_test.c
7285     More verifying workings of read/write mode. Fixing bugs found.
7286
7287     * tests/utils.[ch]
7288     Made these files Autogen generated files.
7289
7290     * tests/util.tpl tests/util.def
7291     New Autogen files to generate utils.[ch]. Moved some generic test functions
7292     into this file. Autogen is such a great tool!
7293
7294 2002-05-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7295
7296     * src/pcm.c src/float_cast.h Win32/config.h
7297     Fixed a couple of Win32 specific bugs pointed out by Michael Fink
7298     (maintainer of WinLAME) and David Viens.
7299
7300     * tests/check_log_buffer.[ch] tests/utils.[ch]
7301     Moved check_log_buffer() to utils.[ch] and deleted old file.
7302
7303 2002-05-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7304
7305     * src/common.[ch] src/sndfile.c
7306     New function psf_default_seek() which will be the default seek function
7307     for things like PCM and floating point data. This default is set for
7308     both read and write in sf_open() but can be over-ridden by any codec
7309     during it's initialisation.
7310
7311 2002-05-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7312
7313     * src/au.c
7314     AU files use a data size value of -1 to mean unknown. Fixed au_open_read()
7315     to allow opening files like this.
7316
7317     * tests/rdwr_test .c
7318     Added more tests.
7319
7320     * src/sndfile.c
7321     Fixed bugs in read/write mode found due to improvements in the test
7322     program.
7323
7324 2002-04-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7325
7326     * tests/rdwr_test .c
7327     New file for testing read/write mode.
7328
7329 2002-04-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7330
7331     * m4/*
7332     Removed all m4 macros from this directory as they get concatenated to form
7333     the file aclocal.m4 anyway.
7334
7335     * sndfile.m4
7336     Moved this from the m4 directory to the root directory asn this is part of
7337     the distribution and is installed during "make install".
7338
7339 2002-04-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7340
7341     * src/float32.c
7342     Removed logging of peaks for all file formats other than AIFF and WAV.
7343
7344     * tests/write_read_test.tpl tests/write_read_test.def
7345     New files which autogen uses to generate write_read_test.c. Doing it this
7346     way makes write_read_test.c far easier to maintain. Other test programs
7347     will be converted to autogen in the near future.
7348
7349     * src/*.c
7350     Fixed a few bugs found when testing on Sparc (bug endian) Solaris.
7351
7352 2002-04-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7353
7354     * doc/*.html
7355     Fixed documention versioning.
7356
7357     * configure.in
7358     Fixed a bug in the routines which search for Large File Support on systems
7359     which have large file support by defualt.
7360
7361 2002-04-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7362
7363     * src/*.[ch]
7364     Found and fixed an issue which can cause a bug in other software (I was
7365     porting Conrad Parker's Sweep program from version 0 of the library to
7366     version 1). When opening a file for write, the libsndfile code would
7367     set the sfinfo.samples field to a maximum value.
7368
7369     * tests/write_read_test.c
7370     Added tests to detect the above problem.
7371
7372 2002-04-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7373
7374     * src/*.[ch]
7375     Finished base implementation of read/write mode. Much more testing still
7376     needed.
7377
7378     * m4/largefile.m4
7379     Macro for detecting Large File Standard capabilities. This macro was ripped
7380     out of the aclocal.m4 file of GNU tar-1.13.
7381
7382     * configure.in
7383     Added detection of large file support. Files larger than 2 Gigabytes should
7384     now be supported on 64 bit platforms and many 32 bit platforms including
7385     Linux (2.4 kernel, glibc-2.2), *BSD, MacOS, Win32.
7386
7387     * libsndfile_convert_version.py
7388     A Python script which attempts to autoconvert code written to use version 0
7389     to version 1.
7390
7391 2002-04-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7392
7393     * src/*.[ch]
7394     Finished base implementation of read/write mode. Much more testing still
7395     needed.
7396
7397     * tests/write_read_test.c
7398     Preliminary tests for read/write mode added. More needed.
7399
7400 2002-04-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7401
7402     * src/sndfile.[ch]
7403     Removed sf_open_read() and sf_open_write() functions,replacting them with
7404     sf_open() which takes an extra mode parameter (SF_OPEN_READ, SF_OPEN_WRITE,
7405     or SF_OPEN_RDWR). This new function sf_open can now be modified to allow
7406     opening a file formodification (RDWR).
7407
7408 2002-04-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7409
7410     * src/*.c
7411     Completed merging of separate xxx_open_read() and xxx_open_write()
7412     functions. All tests pass.
7413
7414 2002-04-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7415
7416     * src/au.c
7417     Massive refactoring required to merge au_open_read() with au_open_write()
7418     to create au_open().
7419
7420 2002-04-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7421
7422     * src/*.c
7423     Started changes required to allow a sound file to be opened in read/write
7424     mode, with separate file pointers for read and write. This involves merging
7425     of encoder/decoder functions like pcm_read_init() and pcm_write_init()
7426     int a new function pcm_init() as well as doing something similar for all
7427     the file type specific functions ie aiff_open_read() and aiff_open_write()
7428     were merged to make the function aiff_open().
7429
7430 2002-04-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7431
7432     * src/file_io.c
7433     New file containing psf_fopen(), psf_fread(), psf_fwrite(), psf_fseek() and
7434     psf_ftell() functions. These function will replace use of fopen/fread/fwrite
7435     etc and allow access to files larger than 2 gigabytes on a number of 32 bit
7436     OSes (Linux on x86, 32 bit Solaris user space apps, Win32 and MacOS).
7437
7438     * src/*.c
7439     Replaced all instances of fopen with psf_open, fread with psd_read, fwrite
7440     with psf_write and so on.
7441
7442 2002-03-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7443
7444     * src/dwvw.c
7445     Finally fixed all known problems with 12, 16 and 24 bit DWVW encoding.
7446
7447     * tests/floating_point_test.c
7448     Added tests for 12, 16 and 24 bit DWVW encoding.
7449
7450 2002-03-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7451
7452     * m4/endian.m4
7453     Defines a new m4 macro AC_C_FIND_ENDIAN, for determining the endian-ness of
7454     the target CPU. It first checks for the definition of BYTE_ORDER in
7455     <endian.h>, then in <sys/types.h> and <sys/param.h>. If none of these work
7456     and the C compiler is not a cross compiler it compiles and runs a program
7457     to test for endian-ness. If the compiler is a cross compiler it makes a
7458     guess based on $target_cpu.
7459
7460     * configure.in
7461     Modified to use AC_C_FIND_ENDIAN.
7462
7463     * src/sfendian.h
7464     Simplified.
7465
7466 2002-02-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7467
7468     * tests/floating_point_test.c
7469     Tests completely rewritten using the dft_cmp function. Now able to
7470     calculate a quick guesstimate of the Signal to Noise Ratio of the encoder.
7471
7472 2002-02-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7473
7474     * tests/dft_cmp.[ch]
7475     New files containing functions for comparing pre and post lossily
7476     compressed data using a quickly hacked DFT.
7477
7478     * tests/utils.[ch]
7479     New files containing functions for saving pre and post encoded data in a
7480     file readable by the GNU Octave package.
7481
7482 2002-02-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7483
7484     * m4/lrint.m4 m4/lrintf.m4
7485     Fixed m4 macros to define HAVE_LRINT and HAVE_LRINTF even when the test
7486     is cached.
7487
7488 2002-02-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7489
7490     * tests/floating_point_test.c
7491     Fixed improper use of strncat ().
7492
7493 2002-02-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7494
7495     * tests/headerless_test.c
7496     New test program to test the ability to open and read a known file type as a
7497     RAW header-less file.
7498
7499 2002-02-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7500
7501     * tests/losy_comp_test.c
7502     Added a test to ensure that the data read from a file is not all zeros.
7503
7504     * examples/sfconvert.c
7505     Added "-gsm610" encoding types.
7506
7507 2002-01-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7508
7509     * examples/sfconvert.c
7510     Added "-dwvw12", "-dwvw16" and "-dwvw24" encoding types.
7511
7512     * tests/dwvw_test.c
7513     New file for testing DWVW encoder/decoder.
7514
7515 2002-01-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7516
7517     * src/dwvw.c
7518     Implemented writing of DWVW. 12 bit seems to work, 16 and 24 bit still broken.
7519
7520     * src/aiff.c
7521     Improved reporting of encoding types.
7522
7523     * src/voc.c
7524     Clean up.
7525
7526 2002-01-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7527
7528     * src/dwvw.c
7529     New file implementing lossless Delta Word Variable Width (DWVW) encoding.
7530     Reading 12 bit DWVW is now working.
7531
7532     * src/aiff.c common.h sndfile.c
7533     Added hooks for DWVW encoded AIFF and RAW files.
7534
7535 2002-01-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7536
7537     * src/w64.c
7538     Robustify header parsing.
7539
7540     * src/wav_w64.h
7541     Header file wav.h was renamed to wav_w64.h to signify sharing of
7542     definitions across the two file types.
7543
7544     * src/wav.c src/w64.c src/wav_w64.c
7545     Refactoring.
7546     Modified and moved functions with a high degree of similarity between
7547     wav.c and w64.c to wav_w64.c.
7548
7549 2002-01-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7550
7551     * src/w64.c
7552     Completed work on getting read and write working.
7553
7554     * examples/sfplay.c
7555     Added code to scale floating point data so it plays at a reasonable volume.
7556
7557     * tests/Makefile.am tests/write_read_test.c
7558     Added tests for W64 files.
7559
7560 2002-01-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7561
7562     * src/*.c
7563     Modded all code in file header writing routines to use
7564     psf_new_binheader_writef().
7565     Removed psf_binheader_writef() from src/common.c.
7566     Globally replaced psf_new_binheader_writef with psf_binheader_writef.
7567
7568 2002-01-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7569
7570     * src/*.c
7571     Modded all code in file parsing routines to use psf_new_binheader_readf().
7572     Removed psf_binheader_readf() from src/common.c.
7573     Globally replaced psf_new_binheader_readf with psf_binheader_readf.
7574
7575     * src/common.[ch]
7576     Added new function psf_new_binheader_writef () which will soon replace
7577     psf_binheader_writef (). The new function has basically the same function
7578     as the original but has a more flexible and capable interface. It also
7579     allows the writing of 64 bit integer values for files contains 64 bit file
7580     offsets.
7581
7582 2002-01-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7583
7584     * src/formats.c src/sndfile.c src/sndfile.h
7585     Added code allowing full enumeration of supported file formats via the
7586     sf_command () interface.
7587     This feature will allow applications to avoid needing recompilation when
7588     support for new file formats are added to libsndfile.
7589
7590     * tests/command_test.c
7591     Added test code for the above feature.
7592
7593     * examples/list_formats.c
7594     New file. An example of the use of the supported file enumeration
7595     interface. This program lists all the major formats and for each major
7596     format the supported subformats.
7597
7598 2002-01-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7599
7600     * src/*.[ch] tests/*.c
7601     Changed command parameter of sf_command () function from a test string to
7602     an int. The valid values for the command parameter begin with SFC_ and are
7603     listed in src/sndfile.h.
7604
7605 2001-12-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7606
7607     * src/formats.c src/sndfile.c
7608     Added an way of enumerating a set of common file formats using the
7609     sf_command () interface. This interface was suggested by Dominic Mazzoni,
7610     one of the main authors of Audacity (http://audacity.sourceforge.net/).
7611
7612 2001-12-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7613
7614     * src/sndfile.c
7615     Added checking of filename parameter in sf_open_read (). Previousy, if a
7616     NULL pointer was passed the library would segfault.
7617
7618 2001-12-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7619
7620     * src/common.c src/common.h
7621     Changed the len parameter of the endswap_*_array () functions from type
7622     int to type long.
7623
7624     * src/pcm.c
7625     Fixed a problem which
7626
7627 2001-12-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7628
7629     * src/sndfile.c
7630     Added conditional #include <sys/types.h> for EMX/gcc on OS/2. Thanks to
7631     Paul Hartman for pointing this out.
7632
7633     * tests/lossy_comp_test.c tests/floating_point_test.c
7634     Added definitions for M_PI for when it isn't defined in <math.h>.
7635
7636 2001-11-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7637
7638     * src/ircam.c
7639     Re-implemented the header reader. Old version was making incorrect
7640     assumptions about the endian-ness of the file from the magic number at the
7641     start of the file. The new code looks at the integer which holds the
7642     number of channels and determines the endian-ness from that.
7643
7644 2001-11-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7645
7646     * src/aiff.c
7647     Added support for other AIFC types ('raw ', 'in32', '23ni').
7648     Further work on IMA ADPCM encoding.
7649
7650 2001-11-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7651
7652     * src/ima_adpcm.c
7653     Renamed from wav_ima_adpcm.c. This file will soon handle IMA ADPCM
7654     encodings for both WAV and AIFF files.
7655
7656     * src/aiff.c
7657     Started adding IMA ADPCM support.
7658
7659 2001-11-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7660
7661     * src/double.c
7662     New file for handling double precision floating point (SF_FORMAT_DOUBLE)
7663     data.
7664
7665     * src/wav.c src/aiff.c src/au.c src/raw.c
7666     Added support for SF_FORMAT_DOUBLE data.
7667
7668     * src/common.[ch]
7669     Addition of endswap_long_array () for endian swapping 64 bit integers. This
7670     function will work correctly on processors with 32 bit and 64 bit longs.
7671     Optimised endswap_short_array () and endswap_int_array ().
7672
7673     * tests/pcm_test.c
7674     Added and extra check. After the first file of each type is written to disk
7675     a checksum is performed of the first 64 bytes and checked against a pre-
7676     calculated value. This will work whatever the endian-ness of the host
7677     machine.
7678
7679 2001-11-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7680
7681     * src/aiff.c
7682     Added handling of u-law, A-law encoded AIFF files. Thanks to Tom Erbe for
7683     supplying example files.
7684
7685     * tests/lossy_comp_test.c
7686     Added tests for above.
7687
7688     * src/common.h src/*.c
7689     Removed function typedefs from common.h and function pointer casting in all
7690     the other files. This allows the compiler to perform proper type checking.
7691     Hopefully this will prevernt problems like the sf_seek bug for OpenBSD,
7692     BeOS etc.
7693
7694     * src/common.[ch]
7695     Added new function psf_new_binheader_readf () which will eventually replace
7696     psf_binheader_readf (). The new function has basically the same function as
7697     the original but has a more flexible and capable interface. It also allows
7698     the reading of 64 bit integer values for files contains 64 bit file
7699     offsets.
7700
7701 2001-11-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7702
7703     * src/voc.c
7704     Completed implementation of VOC file handling. Can now handle 8 and 16 bit
7705     PCM, u-law and A-law files with one or two channels.
7706
7707     * src/write_read_test.c tests/lossy_comp_test.c
7708     Added tests for VOC files.
7709
7710 2001-11-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7711
7712     * src/float_cast.h
7713     Added inline asm version of lrint/lrintf for MacOS. Solution provided by
7714     Stephane Letz.
7715
7716     * src/voc.c
7717     More work on this braindamaged format. The VOC files produced by SoX also
7718     have a number of inconsistencies.
7719
7720 2001-11-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7721
7722     * src/paf.c
7723     Added support for 8 bit PCM PAF files.
7724
7725     * tests/write_read_test.c
7726     Added tests for 8 bit PAF files.
7727
7728 2001-11-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7729
7730     * tests/pcm_test.c
7731     New test program to test for correct scaling of integer values between
7732     different sized integer containers (ie short -> int).
7733     The new specs for libsndfile state that when the source and destination
7734     containers are of a different size, the most significant bit of the source
7735     value becomes the most significant bit of the destination container.
7736
7737     * src/pcm.c src/paf.c
7738     Modified to pass the above test program.
7739
7740     * tests/write_read_test.c tests/lossy_comp_test.c
7741     Modified to work with the new scaling rules.
7742
7743 2001-11-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7744
7745     * src/raw.c tests/write_read_test.c tests/write_read_test.c
7746     Added ability to do raw reads/writes of float, u-law and A-law files.
7747
7748     * src/*.[ch] examples/*.[ch] tests/*.[ch]
7749     Removed dependance on pcmbitwidth field of SF_INFO struct and moved to new
7750     SF_FORMAT_* types and use of SF_ENDIAN_BIG/LITTLE/CPU.
7751
7752 2001-11-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7753
7754     * src/*.[ch]
7755     Started implmentation of major changes documented in doc/version1.html.
7756
7757     Removed all usage of off_t which is not part of the ISO C standard. All
7758     places which were using it are now using type long which is the type of
7759     the offset parameter for the fseek function.
7760     This should fix problems on BeOS, MacOS and *BSD like systems which were
7761     failing "make check" because sizeof (long) != sizeof (off_t).
7762
7763 --------------------------------------------------------------------------------
7764 This is the boundary between version 1 of the library above and version 0 below.
7765 --------------------------------------------------------------------------------
7766
7767 2001-11-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7768
7769     * examples/sfplay_beos.cpp
7770     Added BeOS version of sfplay.c. This needs to be compiled using a C++
7771     compiler so is therefore not built by default. Thanks to Marcus Overhagen
7772     for providing this.
7773
7774 2001-11-10  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7775
7776     * examples/sfplay.c
7777     New example file showing how libsndfile can be used to read and play a
7778     sound file.
7779     At the moment on Linux is supported. Others will follow in the near future.
7780
7781 2001-11-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7782
7783     * src/pcm.c
7784     Fixed problem with normalisation code where a value of 1.0 could map to
7785     a value greater than MAX_SHORT or MAX_INT. Thanks to Roger Dannenberg for
7786     pointing this out.
7787
7788 2001-11-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7789
7790     * src/pcm.c
7791     Fixed scaling issue when reading/writing 8 bit files using
7792     sf_read/sf_write_short ().
7793     On read, values are scaled so that the most significant bit in the char
7794     ends up in the most significant bit of the short. On write, values are
7795     scaled so that most significant bit in the short ends up as the most
7796     significant bit in the char.
7797
7798 2001-11-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7799
7800     * src/au.c src/sndfile.c
7801     Added support for 32 bit float data in big and little endian AU files.
7802
7803     * tests/write_read_test.c
7804     Added tests for 32 bit float data in AU files.
7805
7806 2001-11-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7807
7808     * tests/lossy_comp_test.c
7809     Finalised testing of stereo files where possible.
7810
7811 2001-11-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7812
7813     * src/wav_ms_adpcm.c
7814     Fixed bug in writing stereo MS ADPCM WAV files. Thanks to Xu Xin for
7815     pointing out this problem.
7816
7817 2001-10-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7818
7819     * src/wav_ms_adpcm.c
7820     Modified function srate2blocksize () to handle 44k1Hz stereo files.
7821
7822 2001-10-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7823
7824     * src/w64.c
7825     Added support for Sonic Foundry 64 bit WAV format. As Linux (my main
7826     development platform) does not yet support 64 bit file offsets by default,
7827     current handling of this file format treats everything as 32 bit and fails
7828     openning the file, if it finds anything that goes beyond 32 bit values.
7829
7830     * src/sndfile.[hc] src/common.h src/Makefile.am
7831     Added hooks for W64 support.
7832
7833 2001-10-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7834
7835     * configure.in
7836     Added more warnings options to CFLAGS when the gcc compiler is detected.
7837
7838     * src/*.[ch] tests/*.c examples/*.c
7839     Started fixing the warning messages due to the new CFLASG.
7840
7841     * src/voc.c
7842     More work on VOC file read/writing.
7843
7844     * src/paf.c
7845     Found that PAF files were not checking the normalisation flag when reading
7846     or writing floats and doubles. Fixed it.
7847
7848     * tests/floating_point_test.c
7849     Added specific test for the above problem.
7850
7851     * src/float_cast.h src/pcm.c
7852     Added a section for Win32 to define lrint () and lrintf () in the header
7853     and implement it in the pcm.c
7854
7855 2001-10-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7856
7857     * sndfile-config.in m4/sndfile.m4
7858     These files were donated by Conrad Parker who also provided instructions
7859     on how to install them using autoconf/automake.
7860
7861     * src/float_cast.h
7862     Fiddled around with this file some more. On Linux and other gcc supported
7863     OSes use the C99 functions lrintf() and lrint() for casting from floating
7864     point to int without incurring the huge perfromance penalty (particularly
7865     on the i386 family) caused by the regular C cast from float to int.
7866     These new C99 functions replace the FLOAT_TO_* and DOUBLE_TO_* macros which
7867     I had been playing with.
7868
7869     * configure.in m4/lrint.m4 m4/lrintf.m4
7870     Add detection of these functions.
7871
7872 2001-10-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7873
7874     * src/voc.c
7875     Completed code for reading VOC files containing a single audio data
7876     segment.
7877     Started implementing code to handle files with multiple VOC_SOUND_DATA
7878     segments but couldn't be bothered finishing it. Multiple segment files can
7879     have different sample rates for different sections and other nasties like
7880     silence and repeat segments.
7881
7882 2001-10-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7883
7884     * src/common.h src/*.c
7885     Removed SF_PRIVATE struct field fdata and replaced it with extra_data.
7886
7887     * src/voc.c
7888     Further development of the read part of this woefult file format.
7889
7890 2001-10-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7891
7892     * src/float_cast.h
7893     Implemented gcc and i386 floating point to int cast macros. Standard cast
7894     will be used when not on gcc for i385.
7895
7896     * src/pcm.c
7897     Modified all uses of FLOAT/DOUBLE_TO_INT and FLOAT/DOUBLE_TO_SHORT casts to
7898     comply with macros in float_cast.h.
7899
7900 2001-10-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7901
7902     * src/voc.c
7903     Changed the TYPE_xxx enum names to VOC_TYPE_xxx to prevent name clashes
7904     on MacOS with CodeWarrior 6.0.
7905
7906     * MacOS/MacOS-readme.txt
7907     Updated the compile instructions. Probably still need work as I don't have
7908     access to a Mac.
7909
7910 2001-10-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7911
7912     * src/wav.c src/aiff.c common.c
7913     Changed all references to snprintf to LSF_SNPRINTF and all vsnprintf to
7914     LSF_VSNPRINTF. LSF_VSNPRINTF and LSF_VSNPRINTF are defined in common.h.
7915
7916     * src/common.h
7917     Added checking of HAVE_SNPRINTF and HAVE_VSNPRINTF and defining
7918     LSF_VSNPRINTF and LSF_VSNPRINTF to appropriate values.
7919
7920     * src/missing.c
7921     New file containing a minimal implementation of snprintf and vsnprintf
7922     functions named missing_snprintf and missing_vsnprintf respectively. These
7923     are only compliled into the binary if snprintf and/or vsnprintf are not
7924     available.
7925
7926 2001-09-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7927
7928     * src/ircam.c
7929     New file to handle Berkeley/IRCAM/CARL files.
7930
7931     * src/sndfile.c src/common.h
7932     Modified for IRCAM handling.
7933
7934     * tests/*.c
7935     Added tests for IRCAM files.
7936
7937 2001-09-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7938
7939     * src/wav.c
7940     Apparently microsoft windows (tm) doesn't like ulaw and Alaw WAV files with
7941     20 byte format chunks (contrary to ms's own documentation). Fixed the WAV
7942     header writing code to generate smaller ms compliant ulaw and Alaw WAV
7943     files.
7944
7945 2001-09-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7946
7947     * tests/stdio_test.sh tests/stdio_test.c
7948     Shell script was rewritten as a C program due to incompatibilities of the
7949     sh shell on Linux and Solaris.
7950
7951 2001-09-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7952
7953     * tests/stdio_test.sh tests/stdout_test.c tests/stdin_test.c
7954     New test programs to verify the correct operation of reading from stdin and
7955     writing to stdout.
7956
7957     * src/sndfile.c wav.c au.c nist.c paf.c
7958     Fixed a bugs uncovered by the new test programs above.
7959
7960 2001-09-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7961
7962     * src/sndfile.c wav.c
7963     Fixed a bug preventing reading a file from stdin. Found by T. Narita.

7966
7967     * src/common.h
7968     Fixed a problem on OpenBSD 2.9 which was causing sf_seek() to fail on IMA
7969     WAV files. Root cause was the declaration of the func_seek typedef not
7970     matching the functions it was actually being used to point to. In OpenBSD
7971     sizeof (off_t) != sizeof (int). Thanks to Heikki Korpela for allowing me
7972     to log into his OpenBSD machine to debug this problem.
7973
7974 2001-09-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
7975
7976     * src/sndfile.c
7977     Implemented sf_command ("norm float").
7978
7979     * src/*.c
7980     Implemented handling of sf_command ("set-norm-float"). Float normalization
7981     can now be turned on and off.
7982
7983     * tests/double_test.c
7984     Renamed to floating_point_test.c. Modified to include tests for all scaled
7985     reads and writes of floats and doubles.
7986
7987     * src/au_g72x.c
7988     Fixed bug in normalization code found with improved floating_point_test
7989     program.
7990
7991     * src/wav.c
7992     Added code for parsing 'INFO' and 'LIST' chunks. Will be used for extract
7993     text annotations from WAV files.
7994
7995     * src/aiff.c
7996     Added code for parsing '(c) ' and 'ANNO' chunks. Will be used for extract
7997     text annotations from WAV files.
7998
7999 2001-09-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8000
8001     * examples/sf_info.c example/Makefile.am
8002     Renamed to sndfile_info.c. The program sndfile_info will now be installed
8003     when the library is installed.
8004
8005     * src/float_cast.h
8006     New file defining floating point to short and int casts. These casts will
8007     eventually replace all flot and double casts to short and int. See comments
8008     at the top of the file for the reasoning.
8009
8010     * src/*.c
8011     Changed all default float and double casts to short or int with macros
8012     defined in floatcast.h. At the moment these casts do nothing. They will be
8013     replaced with faster float to int cast operations in the near future.
8014
8015 2001-08-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8016
8017     * tests/command_test.c
8018     New file for testing sf_command () functionality.
8019
8020     * src/sndfile.c
8021     Revisiting of error return values of some functions.
8022     Started implementing sf_command () a new function will allow on-the-fly
8023     modification of library behaviour, or instance, sample value scaling.
8024
8025     * src/common.h
8026     Added hook for format specific sf_command () calls to SNDFILE struct.
8027
8028     * doc/api.html
8029     Updated and errors corrected.
8030
8031     * doc/command.html
8032     New documentation file explaining new sf_command () function.
8033
8034 2001-08-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8035
8036     * src/sndfile.c
8037     Fixed error return values from sf_read*() and sf_write*(). There were
8038     numerous instances of -1 being returned through size_t. These now all set
8039     error int the SF_PRIVATE struct and return 0. Thanks to David Viens for
8040     spotting this.
8041
8042 2001-08-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8043
8044     * src/common.c
8045     Fixed use of va_arg() calls that were causing warning messages with the
8046     latest version of gcc (thanks Maurizio Umberto Puxeddu).
8047
8048 2001-07-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8049
8050     * src/*.c src/sfendian.h
8051     Moved definition of MAKE_MARKER macro to sfendian.h
8052
8053 2001-07-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8054
8055     * src/sndfile.c
8056     Modified sf_get_lib_version () so that version string will be visible using
8057     the Unix strings command.
8058
8059     * examples/Makefile.am examples/sfinfo.c
8060     Renamed sfinfo program and source code to sf_info. This prevents a name
8061     clash with the program included with libaudiofile.
8062
8063 2001-07-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8064
8065     * tests/read_seek_test.c tests/lossy_comp_test.c
8066     Added tests for sf_read_float () and sf_readf_float ().
8067
8068     * src/voc.c
8069     New files for handling Creative Voice files (not complete).
8070
8071     * src/samplitude.c
8072     New files for handling Samplitude files (not complete).
8073
8074 2001-07-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8075
8076     * src/aiff.c src/au.c src/paf.c src/svx.c src/wav.c
8077     Converted these files to using psf_binheader_readf() function. Will soon be
8078     ready to attempt to make reading writing from pipes work reliably.
8079
8080     * src/*.[ch]
8081     Added code for sf_read_float () and sf_readf_float () methods of accessing
8082     file data.
8083
8084 2001-07-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8085
8086     * src/paf.c src/wav_gsm610.c
8087     Removed two printf()s which had escaped notice for some time (thanks
8088     Sigbjørn Skjæret).
8089
8090 2001-07-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8091
8092     * src/wav_gsm610.c
8093     Fixed a bug which prevented GSM 6.10 encoded WAV files generated by
8094     libsndfile from being played in Windoze (thanks klay).
8095
8096 2001-07-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8097
8098     * src/common.[ch]
8099     Implemented psf_binheader_readf() which will do for file header reading what
8100     psf_binheader_writef() did for writing headers. Will eventually allow
8101     libsndfile to read and write from pipes, including named pipes.
8102
8103 2001-07-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8104
8105     * MacOS/config.h Win32/config.h
8106     Attempted to bring these two files uptodate with src/config.h. As I don't
8107     have access to either of these systems support for them may be completely
8108     broken.
8109
8110 2001-06-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8111
8112     * src/float32.c
8113     Fixed bug for big endian processors that can't read 32 bit IEEE floats. Now
8114     tested on Intel x86 and UltraSparc processors.
8115
8116 2001-06-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8117
8118     * src/aiff.c
8119     Modified to allow REX files (from Propellorhead's Recycle and Reason
8120     programs) to be read.
8121     REX files are basically an AIFF file with slightly unusual sequence of
8122     chunks (AIFF files are supposed to allow any sequence) and some extra
8123     application specific information.
8124     Not yet able to write a REX file as the details of the application specific
8125     data is unknown.
8126
8127 2001-06-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8128
8129     * src/wav.c
8130     Fixed endian bug when reading PEAK chunk on big endian machines.
8131
8132     * src/common.c
8133     Fixed endian bug when reading PEAK chunk on big endian machines with
8134     --enable-force-broken-float configure option.
8135     Fix psf_binheader_writef for (FORCE_BROKEN_FLOAT ||______)
8136
8137 2001-06-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8138
8139     * configure.in src/config.h.in
8140     Removed old CAN_READ_WRITE_x86_IEEE configure variable now that float
8141     capabilities are detected at run time.
8142     Added FORCE_BROKEN_FLOAT to allow testing of broken float code on machines
8143     where the processor can in fact handle floats correctly.
8144
8145     * src/float32.c
8146     Rejigged code reading and writing of floats on broken processors.
8147
8148     * m4/
8149     Removed this directory and all its files as they are no longer needed.
8150
8151 2001-06-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8152
8153     * tests/peak_chunk_test.c
8154     New test to validate reading and writing of peak chunk.
8155
8156     * examples/sfconvert
8157     Added -float32 option.
8158
8159     * src/*.c
8160     Changed all error return values to negative values (ie the negative of what
8161     they were).
8162
8163     * src/sndfile.c tests/error_test.c
8164     Modified to take account of the previous change.
8165
8166 2001-06-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8167
8168     * src/float32.c
8169     File renamed from wav_float.c and renamed function to something more
8170     general.
8171     Added runtime detection of floating point capabilities.
8172     Added recording of peaks during write for generation of PEAK chunk.
8173
8174     * src/wav.c src/aiff.c
8175     Added handing for PEAK chunk for floating point files. PEAK is read when the
8176     file headers are read and generated when the file is closed. Logic is in
8177     place for adding PEAK chunk to end of file when writing to a pipe (reading
8178     and writing from/to pipe to be implemented soon).
8179
8180     * src/sndfile.c
8181     Modified sf_signal_max () to use PEAK values if present.
8182
8183 2001-06-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8184
8185     * src/*.c
8186     Added pcm_read_init () and pcm_write_init () to src/pcm.c and removed all
8187     other calls to functions in this file from the filetype specific files.
8188
8189     * src/*.c
8190     Added alaw_read_init (), alaw_write_int (), ulaw_read_init () and
8191     ulaw_write_init () and removed all other calls to functions in alaw.c and
8192     ulaw.c from the filetype specific files.
8193
8194     * tests/write_read_test.c
8195     Added tests to validate sf_seek () on all file types.
8196
8197     * src/raw.c
8198     Implemented raw_seek () function to fix a bug where
8199     sf_seek (file, 0, SEEK_SET) on a RAW file failed.
8200
8201     * src/paf.c
8202     Fixed a bug in paf24_seek () found due to added seeks tests in
8203     tests/write_read_test.c
8204
8205 2001-06-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8206
8207     * tests/read_seek_test.c
8208     Fixed a couple of broken binary files.
8209
8210     * src/aiff.c src/wav.c
8211     Added handling of PEAK chunks on file read.
8212
8213 2001-05-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8214
8215     * check_libsndfile.py
8216     New file for the regression testing of libsndfile.
8217     check_libsndfile.py is a Python script which reads in a file containing
8218     filenames of audio files. Each file is checked by running the examples/sfinfo
8219     program on them and checking for error or warning messages in the libsndfile
8220     log buffer.
8221
8222     * check_libsndfile.list
8223     This is an example list of audio files for use with check_libsndfile.py
8224
8225     * tests/lossy_comp_test.c
8226     Changed the defined value of M_PI for math header files which don't have it.
8227     This fixed validation test failures on MetroWerks compilers. Thanks to Lord
8228     Praetor Satanus of Acheron for bringing this to my attention.
8229
8230 2001-05-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8231
8232     * src/common.[ch]
8233     Removed psf_header_setf () which was no longer required after refactoring
8234     and simplification of header writing.
8235     Added 'z' format specifier to psf_binheader_writef () for zero filling header
8236     with N bytes. Used by paf.c and nist.c
8237
8238     * tests/check_log_buffer.c
8239     New file implementing check_log_buffer () which reads the log buffer of a
8240     SNDFILE* object and searches for error and warning messages. Calls exit ()
8241     if any are found.
8242
8243     * tests/*.c
8244     Added calls to check_log_buffer () after each call to sf_open_XXX ().
8245
8246 2001-05-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8247
8248     * src/wav.c src/wav_ms_adpcm.c src/wav_gsm610.c
8249     Major rehack of header writing using psf_binheader_writef ().
8250
8251 2001-05-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8252
8253     * src/wav.c src/wav_ima_adpcm.c
8254     Major rehack of header writing using psf_binheader_writef ().
8255
8256 2001-05-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8257
8258     * src/wav.c
8259     Changed return type of get_encoding_str () to prevent compiler warnings on
8260     Mac OSX.
8261
8262     * src/aiff.c src/au.c
8263     Major rehack of header writing using psf_binheader_writef ().
8264
8265 2001-05-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8266
8267     * src/common.h src/common.c
8268     Added comments.
8269     Name of log buffer changed from strbuffer to logbuffer.
8270     Name of log buffer index variable changed from strindex to logindex.
8271
8272     * src/*.[ch]
8273     Changed name of internal logging function from psf_sprintf () to
8274     psf_log_printf ().
8275     Changed name of internal header generation functions from
8276     psf_[ab]h_printf () to psf_asciiheader_printf () and
8277     psf_binheader_writef ().
8278     Changed name of internal header manipulation function psf_hsetf () to
8279     psf_header_setf ().
8280
8281 2001-05-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8282
8283     * src/nist.c
8284     Fixed reading and writing of sample_byte_format header. "01" means little
8285     endian and "10" means big endian regardless of bit width.
8286
8287     * configure.in
8288     Detect Mac OSX and disable -Wall and -pedantic gcc options. Mac OSX is
8289     way screwed up and spews out buckets of warning messages from the system
8290     headers.
8291     Added --disable-gcc-opt configure option (sets gcc optimisation to -O0 ) for
8292     easier debugging.
8293     Made decision to harmonise source code version number and .so library
8294     version number. Future releases will stick to this rule.
8295
8296     * doc/new_file_type.HOWTO
8297     New file to document the addition of new file types to libsndfile.
8298
8299 2001-05-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8300
8301     * src/nist.c
8302     New file for reading/writing Sphere NIST audio file format.
8303     Originally requested by Elis Pomales in 1999.
8304     Retrieved from unstable (and untouched for 18 months) branch of libsndfile.
8305     Some vital information gleaned from the source code to Bill Schottstaedt's
8306     sndlib library : ftp://ccrma-ftp.stanford.edu/pub/Lisp/sndlib.tar.gz
8307     Currently reading and writing 16, 24 and 32 bit, big-endian and little
8308     endian, stereo and mono files.
8309
8310     * src/common.h src/common.c
8311     Added psf_ah_printf () function to help construction of ASCII headers (ie NIST).
8312
8313     * configure.in
8314     Added test for vsnprintf () required by psf_ah_printf ().
8315
8316     * tests/write_read_test.c
8317     Added tests for supported NIST files.
8318
8319 2001-05-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8320
8321     * tests/write_read_test.c
8322     Added tests for little endian AIFC files.
8323
8324     * src/aiff.c
8325     Minor re-working of aiff_open_write ().
8326     Added write support for little endian PCM encoded AIFC files.
8327
8328 2001-05-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8329
8330     * src/aiff.c
8331     Minor re-working of aiff_open_read ().
8332     Added read support for little endian PCM encoded AIFC files from the Mac
8333     OSX CD ripper program. Guillaume Lessard provided a couple of sample files
8334     and a working patch.
8335     The patch was not used as is but gave a good guide as to what to do.
8336
8337 2001-05-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8338
8339     * src/sndfile.h
8340     Fixed comments about endian-ness of WAV and AIFF files. Guillaume Lessard
8341     pointed out the error.
8342
8343 2001-04-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8344
8345     * examples/make_sine.c
8346     Re-write of this example using sample rate and required frequency in Hz.
8347
8348 2001-02-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8349
8350     * src/sndfile.c
8351     Fixed bug that prevented known file types from being read as RAW PCM data.
8352
8353 2000-12-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8354
8355     * src/aiff.c
8356     Added handing of COMT chunk.
8357
8358 2000-11-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8359
8360     * examples/sfconvert.c
8361     Fixed bug in normalisatio code. Pointed out by Johnny Wu.
8362
8363 2000-11-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8364
8365     * Win32/config.h
8366     Fixed the incorrect setting of HAVE_ENDIAN_H parameter. Win32 only issue.
8367
8368 2000-10-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8369
8370     * tests/Makefile.am
8371     Added -lm for write_read_test_LDADD.
8372
8373 2000-10-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8374
8375     * src/sndfile.c src/au.c
8376     Fixed bug which prevented writing of G723 24kbps AU files.
8377
8378     * tests/lossy_comp_test.c
8379     Corrrection to options for G723 tests.
8380
8381     * configure.in
8382     Added --disable-gcc-pipe option for DJGPP compiler (gcc on MS-DOS) which
8383     doesn't allow gcc -pipe option.
8384

8460
8461     * src/G72x/*
8462     New files for reading/writing G721 and G723 ADPCM audio. These files
8463     are from a Sun Microsystems reference implementation released under a
8464     free software licence.
8465     Extensive changes to this code to make it fit in with libsndfile.
8466     See the ChangeLog in this directory for details.
8467
8468     * src/au_g72x.c
8469     New file for G721 encoded AU files.
8470
8471 2000-07-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8472
8473     * libsndfile.spec.in

8475
8476 2000-06-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8477
8478     * src/sndfile.c src/sndfile.h
8479     Add checking for and handling of header-less u-law encoded AU/SND files.
8480     Any file with a ".au" or ".snd" file extension and without the normal
8481     AU file header is treated as an 8kHz, u-law encoded file.
8482
8483     * src/au.h
8484     New function for opening a headerless u-law encoded file for read.
8485
8486 2000-06-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8487
8488     * src/paf.c

8490
8491 2000-06-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8492
8493     * tests/write_read_test.c
8494     Added extra sf_perror() calls when sf_write_XXXX fails.
8495
8496 2000-05-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8497
8498     * src/common.c
8499     Modified usage of va_arg() macro to work correctly on PowerPC
8500     Linux. Thanks to Kyle Wheeler for giving me ssh access to his
8501     machine while I was trying to track this down.
8502
8503     * configure.in src/*.[ch]
8504     Sorted out some endian-ness issues brought up by PowerPC Linux.
8505
8506     * tests/read_seek_test.c
8507     Added extra debugging for when tests fail.
8508
8509 2000-05-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8510
8511     * src/wav.c
8512     Fixed bug in GSM 6.10 handling for big-endian machines. Thanks
8513     to Sigbjørn Skjæret for reporting this.
8514
8515 2000-04-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8516
8517     * src/sndfile.c src/wav.c src/wav_gsm610.c
8518     Finallised writing of GSM 6.10 WAV files.
8519

8530
8531 2000-03-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8532
8533     * configure.in
8534     Fixed --enable-justsrc option.
8535
8536 2000-03-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8537
8538     * wav.c
8539     Fixed checking of bytespersec field of header. Still some weirdness
8540     with some files.
8541
8542 2000-03-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8543
8544     * tests/lossy_comp_test.c
8545     Added option to test PCM WAV files (sanity check).
8546     Fixed bug in sf_seek() tests.
8547
8548 2000-02-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8549
8550     * src/sndfile.c src/wav.c
8551     Minor changes to allow writing of GSM 6.10 WAV files.
8552
8553 2000-02-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8554
8555     * configure.in Makefile.am src/Makefile.am
8556     Finally got around to figuring out how to build a single library from
8557     multiple source directories.
8558     Reading GSM 6.10 files now seems to work.
8559
8560 2000-01-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8561
8562     * src/wav.c
8563     Added more error reporting in read_fmt_chunk().
8564
8565 1999-12-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8566
8567     * examples/sfinfo.c
8568     Modified program to accept multiple filenames from the command line.
8569
8570 1999-11-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8571
8572     * src/wav_ima_adpcm.c
8573     Moved code around in preparation to adding ability to read/write IMA ADPCM
8574     encoded AIFF files.
8575
8576 1999-11-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8577
8578     * src/common.c
8579     Fixed put_int() and put_short() macros used by _psf_hprintf() which were
8580     causing seg. faults on Sparc Solaris.
8581
8582 1999-11-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8583
8584     * src/common.c
8585     Added string.h to includes. Thanks to Sigbjxrn Skjfret.
8586
8587     * src/svx.c
8588     Fixed __svx_close() function to ensure FORM and BODY chunks are correctly
8589     set.
8590
8591 1999-10-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8592
8593     * src/au.c
8594     Fixed handling of incorrect size field in AU header on read. Thanks to
8595     Christoph Lauer for finding this problem.
8596
8597 1999-09-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8598
8599     * src/aiff.c
8600     Fixed a bug with incorrect SSND chunk length being written. This also lead
8601     to finding an minor error in AIFF header parsing. Thanks to Dan Timis for
8602     pointing this out.
8603
8604 1999-09-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8605
8606     * src/paf.c
8607     Fixed a bug with reading and writing 24 bit stereo PAF files. This problem
8608     came to light when implementing tests for the new functions which operate
8609     in terms of frames rather than items.
8610
8611 1999-09-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8612
8613     * src/sndfile.c
8614     Modified file type detection to use first 12 bytes of file rather than
8615     file name extension. Required this because NIST files use the same
8616     filename extension as Microsoft WAV files.
8617
8618     * src/sndfile.c src/sndfile.h
8619     Added short, int and double read/write functions which work in frames
8620     rather than items. This was originally suggested by Maurizio Umberto
8621     Puxeddu.
8622
8623 1999-09-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8624
8625     * src/svx.c
8626     Finished off implementation of write using __psf_hprintf().
8627
8628 1999-09-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8629
8630     * src/common.h
8631     Added a buffer to SF_PRIVATE for writing the header. This is required
8632     to make generating headers for IFF/SVX files easier as well as making
8633     it easier to do re-write the headers which will be required when
8634     sf_rewrite_header() is implemented.
8635
8636     * src/common.c
8637     Implemented __psf_hprintf() function. This is an internal function
8638     which is documented briefly just above the code.
8639
8640 1999-09-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8641
8642     * src/sndfile.c
8643     Fixed a bug in sf_write_raw() where it was returning incorrect values
8644     (thanks to Richard Dobson for finding this one). Must put in a test
8645     routine for sf_read_raw and sf_write_raw.
8646
8647     * src/aiff.c
8648     Fixed default FORMsize in __aiff_open_write ().
8649
8650     * src/sndfile.c
8651     Added copy of filename to internal data structure. IFF/SVX files
8652     contain a NAME header chunk. Both sf_open_read() and sf_open_write()
8653     copy the file name (less the leading path information) to the
8654     filename field.
8655
8656     * src/svx.c
8657     Started implementing writing of files.
8658
8659 1999-08-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8660
8661     * src/svx.c
8662     New file for reading/writing 8SVX and 16SVX files.
8663
8664     * src/sndfile.[ch] src/common.h
8665     Changes for SVX files.
8666
8667     * src/aiff.c
8668     Fixed header parsing when unknown chunk is found.
8669
8670 1999-08-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8671
8672     * src/paf.c
8673     New file for reading/writing Ensoniq PARIS audio file format.
8674
8675     * src/sndfile.[ch] src/common.h
8676     Changes for PAF files.
8677
8678     * src/sndfile.[ch]
8679     Added stuff for sf_get_lib_version() function.
8680
8681
8682 1999-07-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8683
8684     * src/sndfile.h MacOS/config.h
8685     Fixed minor MacOS configuration issues.
8686
8687 1999-07-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8688
8689     * MacOS/
8690     Added a new directory for the MacOS config.h file and the
8691     readme file.
8692
8693     * src/aiff.c
8694     Fixed calculation of datalength when reading SSND chunk. Thanks to
8695     Sigbjørn Skjæret for pointing out this error.
8696
8697 1999-07-29  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8698
8699     * src/sndfile.c src/sndfile.h src/raw.c
8700     Further fixing of #includes for MacOS.
8701
8702 1999-07-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8703
8704     * src/wav.c src/aiff.c
8705     Added call to ferror () in main header parsing loop of __XXX_open_read
8706     functions. This should fix problems on platforms (MacOS, AmigaOS) where
8707     fseek()ing or fread()ing beyond the end of the file puts the FILE*
8708     stream in an error state until clearerr() is called.
8709
8710     * tests/write_read_test.c
8711     Added tests for RAW header-less PCM files.
8712
8713     * src/common.h
8714     Moved definition of struct tribyte to pcm.c which is the only place
8715     which needs it.
8716
8717     * src/pcm.c
8718     Modified all code which assumed sizeof (struct tribyte) == 3. This code
8719     did not work on MacOS. Thanks to Ben "Jacobs" for pointing this out.
8720
8721     * src/au.c
8722     Removed <sys/stat.h> from list of #includes (not being used).
8723
8724     * src/sndfile.c
8725     Added MacOS specific #ifdef to replace <sys/stat.h>.
8726
8727     * src/sndfile.h
8728     Added MacOS specific #ifdef to replace <sys/stat.h>.
8729
8730     * src/sndfile.h
8731     Added MacOS specific typedef for off_t.
8732
8733     * MacOS-readme.txt
8734     New file with instructions for building libsndfile under MacOS. Thanks
8735     to Ben "Jacobs" for supplying these instructions.
8736
8737 1999-07-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8738
8739     * configure.in
8740     Removed sndfile.h from generated file list as there were no longer
8741     any autoconf substitutions being made.
8742
8743     * src/raw.c
8744     New file for handling raw header-less PCM files. In order to open these
8745     for read, the user must specify format, pcmbitwidth and channels in the
8746     SF_INFO struct when calling sf_open_read ().
8747
8748     * src/sndfile.c
8749     Added support for raw header-less PCM files.
8750
8751 1999-07-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8752
8753     * examples/sfinfo.c
8754     Removed options so the sfinfo program always prints out all the information.
8755
8756 1999-07-19  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8757
8758     * src/alaw.c
8759     New file for A-law encoding (similar to u-law).
8760
8761     * tests/alaw_test.c
8762     New test program to test the A-law encode/decode lookup tables.
8763
8764     * tests/lossy_comp_test.c
8765     Added tests for a-law encoded WAV, AU and AULE files.
8766
8767 1999-07-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8768
8769     * src/sndfile.c src/au.c
8770     Removed second "#include <unistd.h>". Thanks to Ben "Jacobs" for pointing
8771     this out.
8772
8773 1999-07-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8774
8775     * tests/ulaw_test.c
8776     New test program to test the u-law encode/decode lookup tables.
8777
8778 1999-07-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8779
8780     * src/sndfile.h
8781     Made corrections to comments on the return values from sf_seek ().
8782
8783     * src/sndfile.c
8784     Fixed boundary condition checking bug and accounting bug in sf_read_raw ().
8785
8786 1999-07-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8787
8788     * src/au.c src/ulaw.c
8789     Finished implementation of u-law encoded AU files.
8790
8791     * src/wav.c
8792     Implemented reading and writing of u-law encoded WAV files.
8793
8794     * tests/
8795     Changed name of adpcm_test.c to lossy_comp_test.c. This test program
8796     will now be used to test Ulaw and Alaw encoding as well as APDCM.
8797     Added tests for Ulaw encoded WAV files.
8798
8799 1999-07-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8800
8801     * tests/adpcm_test.c
8802     Initialised amp variable in gen_signal() to remove compiler warning.
8803
8804 1999-07-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8805
8806     * src/aiff.c
8807     In __aiff_open_read () prevented fseek()ing beyond end of file which
8808     was causing trouble on MacOS with the MetroWerks compiler. Thanks to
8809     Ben "Jacobs" for pointing this out.
8810
8811     *src/wav.c
8812     Fixed as above in __wav_open_read ().
8813
8814 1999-07-01    Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8815
8816     * src/wav_ms_adpcm.c
8817     Implemented MS ADPCM encoding. Code cleanup of decoder.
8818
8819     * tests/adpcm_test.c
8820     Added tests for MS ADPCM WAV files.
8821
8822     * src/wav_ima_adpcm.c
8823     Fixed incorrect parameter in call to srate2blocksize () from
8824     __ima_writer_init ().
8825
8826 1999-06-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8827
8828     * tests/read_seek_test.c
8829     Added test for 8 bit AIFF files.
8830
8831 1999-06-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8832
8833     * tests/write_read_test.c
8834     Removed test for IMA ADPCM WAV files which is now done in adpcm_test.c
8835
8836     * configure.in
8837     Added -Wconversion to CFLAGS.
8838
8839     * src/*.c tests/*.c examples/*.c
8840     Fixed all warnings resulting from use of -Wconversion.
8841
8842 1999-06-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8843
8844     * src/wav.c
8845     Added fact chunk handling on read and write for all non WAVE_FORMAT_PCM
8846     WAV files.
8847
8848     * src/wav_ima.c
8849     Changed block alignment to be dependant on sample rate. This should make
8850     WAV files created with libsndfile compatible with the MS Windows media
8851     players.
8852
8853     * tests/adpcm_test.c
8854     Reimplemented adpcm_test_short and implemented adpcm_test_int and
8855     adpcm_test_double.
8856     Now have full testing of IMA ADPCM WAV file read, write and seek.
8857
8858 1999-06-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8859
8860     * src/wav_float.c
8861     Fixed function prototype for x86f2d_array () which was causing ocassional
8862     seg. faults on Sparc Solaris machines.
8863
8864 1999-06-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8865
8866     * src/aiff.c
8867     Fixed bug in __aiff_close where the length fields in the header were
8868     not being correctly calculated before writing.
8869
8870     * tests/write_read_test.c
8871     Modified to detect the above bug in WAV, AIFF and AU files.
8872
8873 1999-06-12    Erik de Castro Lopo     <erikd AT mega-nerd DOT com>
8874
8875     * Win32/*
8876     Added a contribution from Albert Faber to allow libsndfile to compile
8877     under Win32 systems. libsndfile will now be used as part of LAME the
8878     the MPEG 1 Layer 3 encoder (http://internet.roadrunner.com/~mt/mp3/).
8879
8880 1999-06-11    Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8881
8882     * configure.in
8883     Changed to reflect previous changes.
8884
8885     * src/wav_ima_adpcm.c
8886     Fixed incorrect calculation of bytespersec header field (IMA ADPCM only).
8887
8888     Fixed bug when writing from int or double data to IMA ADPCM file. Will need
8889     to write test code for this.
8890
8891     Fixed bug in __ima_write () whereby the length of the current block was
8892     calculated incorrectly. Thanks to Jongcheon Park for pointing this out.
8893
8894 1999-03-27  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8895
8896     * src/*.c
8897     Changed all read/write/lseek function calls to fread/fwrite/
8898     fseek/ftell and added error checking of return values from
8899     fread and fwrite in critical areas of the code.
8900
8901     * src/au.c
8902     Fixed incorrect datasize element in AU header on write.
8903
8904     * tests/error_test.c
8905     Add new test to check all error values have an associated error
8906     string. This will avoid embarrassing real world core dumps.
8907
8908 1999-03-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8909
8910     * src/wav.c src/aiff.c
8911     Added handling for unknown chunk markers in the file.
8912
8913 1999-03-22  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8914
8915     * src/sndfile.c
8916     Filled in missing error strings in SndfileErrors array. Missing entries
8917     can cause core dumps when calling sf_error-str (). Thanks to Sam
8918     <mrsam at-sign geocities.com> for finding this problem.
8919
8920 1999-03-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8921
8922     * src/wav_ima_adpcm.c
8923     Work on wav_ms_adpcm.c uncovered a bug in __ima_read () when reading
8924     stereo files. Caused by not adjusting offset into buffer of decoded
8925     samples for 2 channels. A similar bug existed in __ima_write ().
8926     Need a test for stereo ADPCM files.
8927
8928     * src/wav_ms_adpcm.c
8929     Decoder working correctly.
8930
8931 1999-03-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8932
8933     * configure.in Makefile.am
8934     Added --enable-justsrc configuration variable sent by Sam
8935     <mrsam at-sign geocities.com>.
8936
8937     * src/wav_ima_adpcm.c
8938     Fixed bug when reading beyond end of data section due to not
8939     checking pima->blockcount.
8940     This uncovered __ima_seek () bug due to pima->blockcount being set
8941     before calling __ima_init_block ().
8942
8943 1999-03-17  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8944
8945     * src/wav.c
8946     Started implementing MS ADPCM decoder.
8947     If file is WAVE_FORMAT_ADPCM and length of data chunk is odd, this
8948     encoder seems to add an extra byte. Why not just give an even data
8949     length?
8950
8951 1999-03-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8952
8953     * src/wav.c
8954     Split code out of wav.c to create wav_float.c and wav_ima_adpcm.c.
8955     This will make it easier to add and debug other kinds of WAV files
8956     in future.
8957
8958 1999-03-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8959
8960     * tests/
8961     Added adpcm_test.c which implements test functions for
8962     IMA ADPCM reading/writing/seeking etc.
8963
8964     * src/wav.c
8965     Fixed many bugs in IMA ADPCM encoder and decoder.
8966
8967 1999-03-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8968
8969     * src/wav.c
8970     Finished implementing IMA ADPCM encoder and decoder (what a bitch!).
8971
8972 1999-03-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8973
8974     * src/wav.c
8975     Started implementing IMA ADPCM decoder.
8976
8977 1999-03-02  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8978
8979     * src/sndfile.c
8980     Fixed bug where the sf_read_XXX functions were returning a
8981     incorrect read count when reading past end of file.
8982     Fixed bug in sf_seek () when seeking backwards from end of file.
8983
8984     * tests/read_seek_test.c
8985     Added multiple read test to short_test(), int_test () and
8986     double_test ().
8987     Added extra chunk to all test WAV files to test that reading
8988     stops at end of 'data' chunk.
8989
8990 1999-02-21  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8991
8992     * tests/write_read_test.c
8993     Added tests for little DEC endian AU files.
8994
8995     * src/au.c
8996     Add handling for DEC format little endian AU files.
8997
8998 1999-02-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
8999
9000     * src/aiff.c src/au.c src/wav.c
9001     Add __psf_sprintf calls during header parsing.
9002
9003     * src/sndfile.c src/common.c
9004     Implement sf_header_info (sndfile.c) function and __psf_sprintf (common.c).
9005
9006     * tests/write_read_test.c
9007     Added tests for 8 bit PCM files (WAV, AIFF and AU).
9008
9009     * src/au.c src/aiff.c
9010     Add handling of 8 bit PCM data format.
9011
9012     * src/aiff.c
9013     On write, set blocksize in SSND chunk to zero like everybody else.
9014
9015 1999-02-16  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
9016
9017     * src/pcm.c:
9018     Fixed bug in let2s_array (cptr was not being initialised).
9019
9020     * src/sndfile.c:
9021     Fixed bug in sf_read_raw and sf_write_raw. sf_seek should
9022     now work when using these functions.
9023
9024 1999-02-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
9025
9026     * tests/write_read_test.c:
9027     Force test_buffer array to be double aligned. Sparc Solaris
9028     requires this.
9029
9030 1999-02-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
9031
9032     * src/pcm.c:
9033     Fixed a bug which was causing errors in the reading
9034     and writing of 24 bit PCM files.
9035

9040
9041     * src/aiff.c:
9042     Changed reading of 'COMM' chunk to avoid reading an int
9043     which overlaps an int (4 byte) boundary.
9044
