dir: /common/libsndfile/ChangeLog/
2001-11-11 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* examples/sfplay_beos.cpp
Added BeOS version of sfplay.c. This needs to be compiled using a C++
compiler so is therefore not built by default. Thanks to Marcus Overhagen
for providing this.
2001-11-11 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/*.[ch]
Removed all usage of off_t which is not part of the ISO C standard. All places
which were using it are now using type long which is the type of the offset
parameter for the fseek function.
This should fix problems on BeOS, MacOS and *BSD like systems which were failing
"make check" because sizeof (long) != sizeof (off_t).
2001-11-10 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* examples/sfplay.c
New example file showing how libsndfile can be used to read and play a sound file.
At the moment on Linux is supported. Others will follow in the near future.
2001-11-08 Erik de Castro Lopo <erikd AT zip DOT com DOT au>

out this problem.
2001-10-24 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav_ms_adpcm.c
Modified function srate2blocksize () to handle 44k1Hz stereo files.
2001-10-24 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/lossy_comp_test.c
Modified this test program so that for stereo capable files, test stereo mode
instead of mono.
2001-10-06 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.h
Win32 has _snprintf and _vsnprintf but not snprintf and vsnprintf. Added a
conditional #define to fix this.
2001-10-04 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/voc.c
Changed the TYPE_xxx enum names to VOC_TYPE_xxx to prevent name clashes
on MacOS with CodeWarrior 6.0.
* MacOS/MacOS-readme.txt
Updated the compile instructions. Probably still need work as I don't have
access to a Mac.
2001-10-01 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c src/aiff.c common.c
Changed all references to snprintf to LSF_SNPRINTF and all vsnprintf to
LSF_VSNPRINTF. LSF_VSNPRINTF and LSF_VSNPRINTF are defined in common.h.
* src/common.h
Added checking of HAVE_SNPRINTF and HAVE_VSNPRINTF and defining LSF_VSNPRINTF
and LSF_VSNPRINTF to appropriate values.
* src/missing.c
New file containing a minimal implementation of snprintf and vsnprintf functions
named missing_snprintf and missing_vsnprintf respectively. These are only
compliled into the binary if snprintf and/or vsnprintf are not available.
2001-09-29 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/ircam.c
New file to handle Berkeley/IRCAM/CARL files.
* src/sndfile.c src/common.h
Modified for IRCAM handling.
* tests/*.c
Added tests for IRCAM files.
2001-09-27 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c
Apparently microsoft windows (tm) doesn't like ulaw and Alaw WAV files with
20 byte format chunks (contrary to ms's own documentation). Fixed the WAV
header writing code to generate smaller ms compliant ulaw and Alaw WAV files.
2001-09-17 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/stdio_test.sh tests/stdio_test.c
Shell script was rewritten as a C program due to incompatibilities of the sh
shell on Linux and Solaris.
2001-09-16 Erik de Castro Lopo <erikd AT zip DOT com DOT au>

Fixed a bug preventing reading a file from stdin. Found by T. Narita.
2001-09-12 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.h
Fixed a problem on OpenBSD 2.9 which was causing sf_seek() to fail on IMA WAV
files. Root cause was the declaration of the func_seek typedef not matching the
functions it was actually being used to point to. In OpenBSD sizeof (off_t) !=
sizeof (int). Thanks to Heikki Korpela for allowing me to log into his OpenBSD
machine to debug this problem.
2001-09-03 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/sndfile.c
Implemented sf_command ("norm float").
* src/*.c
Implemented handling of sf_command ("norm float"). Float normalization can now
be turned on and off.
* tests/double_test.c
Renamed to floating_point_test.c. Modified to include tests for all scaled reads
and writes of floats and doubles.
* src/au_g72x.c
Fixed bug in normalization code found with improved floating_point_test program.
* src/wav.c
Added code for parsing 'INFO' and 'LIST' chunks. Will be used for extract text
annotations from WAV files.
* src/aiff.c
Added code for parsing '(c) ' and 'ANNO' chunks. Will be used for extract text
annotations from WAV files.
2001-09-02 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* examples/sf_info.c example/Makefile.am
Renamed to sndfile_info.c. The program sndfile_info will now be installed when the
library is installed.
* src/floatcast.h
New file defining floating point to short and int casts. These casts will
eventually replace all flot and double casts to short and int. See comments at
the top of the file for the reasoning.
* src/*.c
Changed all default float and double casts to short or int with macros defined
in floatcast.h. At the moment these casts do nothing. They will be replaced
with faster float to int cast operations in the near future.
2001-08-31 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/command_test.c
New file for testing sf_command () functionality.
* src/sndfile.c
Revisiting of error return values of some functions.
Started implementing sf_command () a new function will allow on-the-fly modification
of library behaviour, or instance, sample value scaling.
* src/common.h
Added hook for format specific sf_command () calls to SNDFILE struct.
* doc/api.html
Updated and errors corrected.
* doc/command.html
New documentation file explaining new sf_command () function.
2001-08-11 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/sndfile.c
Fixed error return values from sf_read*() and sf_write*(). There were numerous
instances of -1 being returned through size_t. These now all set error int the
SF_PRIVATE struct and return 0. Thanks to David Viens for spotting this.
2001-08-01 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.c
Fixed use of va_arg() calls that were causing warning messages with the latest
version of gcc (thanks Maurizio Umberto Puxeddu).
2001-07-25 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/*.c src/sfendian.h
Moved definition of MAKE_MARKER macro to sfendian.h
2001-07-23 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/sndfile.c
Modified sf_get_lib_version () so that version string will be visible using the
Unix strings command.
* examples/Makefile.am examples/sfinfo.c
Renamed sfinfo program and source code to sf_info. This prevents a name clash
with the program included with libaudiofile.
2001-07-22 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/read_seek_test.c tests/lossy_comp_test.c

Added code for sf_read_float () and sf_readf_float () methods of accessing
file data.
2001-07-20 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/paf.c src/wav_gsm610.c

Skj�ret).
2001-07-19 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav_gsm610.c
Fixed a bug which prevented GSM 6.10 encoded WAV files generated by libsndfile from
being played in Windoze (thanks klay).
2001-07-18 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.[ch]
Implemented psf_binheader_readf() which will do for file header reading what
psf_binheader_writef() did for writing headers. Will eventually allow
libsndfile to read and write from pipes, including named pipes.
2001-07-16 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* MacOS/config.h Win32/config.h
Attempted to bring these two files uptodate with src/config.h. As I don't have
access to either of these systems support for them may be completely broken.
2001-06-18 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/float32.c
Fixed bug for big endian processors that can't read 32 bit IEEE floats. Now tested
on Intel x86 and UltraSparc processors.
2001-06-13 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/aiff.c
Modified to allow REX files (from Propellorhead's Recycle and Reason programs) to
be read.
REX files are basically an AIFF file with slightly unusual sequence of chunks
(AIFF files are supposed to allow any sequence) and some extra application
specific information.
Not yet able to write a REX file as the details of the application specific
data is unknown.
2001-06-12 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c
Fixed endian bug when reading PEAK chunk on big endian machines.
* src/common.c

* tests/peak_chunk_test.c
New test to validate reading and writing of peak chunk.
* examples/sfconvert
Added -float32 option.

Added runtime detection of floating point capabilities.
Added recording of peaks during write for generation of PEAK chunk.
* src/wav.c src/aiff.c
Added handing for PEAK chunk for floating point files. PEAK is read when the
file headers are read and generated when the file is closed. Logic is in place
for adding PEAK chunk to end of file when writing to a pipe (reading and writing
from/to pipe to be implemented soon).
* src/sndfile.c
Modified sf_signal_max () to use PEAK values if present.
2001-06-03 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/*.c
Added pcm_read_init () and pcm_write_init () to src/pcm.c and removed all other calls
to functions in this file from the filetype specific files.

Added tests to validate sf_seek () on all file types.
* src/raw.c
Implemented raw_seek () function to fix a bug where sf_seek (file, 0, SEEK_SET) on a
RAW file failed.
* src/paf.c
Fixed a bug in paf24_seek () found due to added seeks tests in tests/write_read_test.c
2001-06-01 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/read_seek_test.c
Fixed a couple of broken binary files.
* src/aiff.c src/wav.c
Added handling of PEAK chunks on file read.
2001-05-31 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* check_libsndfile.py
New file for the regression testing of libsndfile.
check_libsndfile.py is a Python script which reads in a file containing
filenames of audio files. Each file is checked by running the examples/sfinfo
program on them and checking for error or warning messages in the libsndfile
log buffer.
* check_libsndfile.list
This is an example list of audio files for use with check_libsndfile.py
* tests/lossy_comp_test.c
Changed the defined value of M_PI for math header files which don't have it.
This fixed validation test failures on MetroWerks compilers. Thanks to Lord
Praetor Satanus of Acheron for bringing this to my attention.
2001-05-30 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.[ch]
Removed psf_header_setf () which was no longer required after refactoring
and simplification of header writing.
Added 'z' format specifier to psf_binheader_writef () for zero filling header
with N bytes. Used by paf.c and nist.c

New file implementing check_log_buffer () which reads the log buffer of a SNDFILE*
object and searches for error and warning messages. Calls exit () if any are found.
* tests/*.c
Added calls to check_log_buffer () after each call to sf_open_XXX ().
2001-05-29 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c src/wav_ms_adpcm.c src/wav_gsm610.c

Added comments.
Name of log buffer changed from strbuffer to logbuffer.
Name of log buffer index variable changed from strindex to logindex.
* src/*.[ch]
Changed name of internal logging function from psf_sprintf () to psf_log_printf ().
Changed name of internal header generation functions from psf_[ab]h_printf () to
psf_asciiheader_printf () and psf_binheader_writef ().
Changed name of internal header manipulation function psf_hsetf () to
psf_header_setf ().
2001-05-24 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/nist.c
Fixed reading and writing of sample_byte_format header. "01" means little endian
and "10" means big endian regardless of bit width.
* configure.in
Detect Mac OSX and disable -Wall and -pedantic gcc options. Mac OSX is way screwed
up and spews out buckets of warning messages from the system headers.
Added --disable-gcc-opt configure option (sets gcc optimisation to -O0 ) for
easier debugging.
Made decision to harmonise source code version number and .so library version
number. Future releases will stick to this rule.
* doc/new_file_type.HOWTO
New file to document the addition of new file types to libsndfile.

2000-01-03 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c
Added more error reporting in read_fmt_chunk().
1999-12-21 Erik de Castro Lopo <erikd AT zip DOT com DOT au>

Moved code around in preparation to adding ability to read/write IMA ADPCM
encoded AIFF files.
1999-11-16 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.c
Fixed put_int() and put_short() macros used by _psf_hprintf() which were
causing seg. faults on Sparc Solaris.
1999-11-15 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.c
Added string.h to includes. Thanks to Sigbjxrn Skjfret.

Fixed __svx_close() function to ensure FORM and BODY chunks are correctly
set.
1999-10-01 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/au.c
Fixed handling of incorrect size field in AU header on read. Thanks to
Christoph Lauer for finding this problem.
1999-09-28 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/aiff.c
Fixed a bug with incorrect SSND chunk length being written. This also lead
to finding an minor error in AIFF header parsing. Thanks to Dan Timis for
pointing this out.
1999-09-24 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/paf.c
Fixed a bug with reading and writing 24 bit stereo PAF files. This problem
came to light when implementing tests for the new functions which operate
in terms of frames rather than items.
1999-09-23 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/sndfile.c
Modified file type detection to use first 12 bytes of file rather than
file name extension. Required this because NIST files use the same
filename extension as Microsoft WAV files.
* src/sndfile.c src/sndfile.h
Added short, int and double read/write functions which work in frames rather
than items. This was originally suggested by Maurizio Umberto Puxeddu
1999-09-22 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/svx.c
Finished off implementation of write using __psf_hprintf().
1999-09-21 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/common.h
Added a buffer to SF_PRIVATE for writing the header. This is required
to make generating headers for IFF/SVX files easier as well as making
it easier to do re-write the headers which will be required when
sf_rewrite_header() is implemented.
* src/common.c
Implemented __psf_hprintf() function. This is an internal function
which is documented briefly just above the code.
1999-09-05 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/sndfile.c
Fixed a bug in sf_write_raw() where it was returning incorrect values
(thanks to Richard Dobson for finding this one). Must put in a test
routine for sf_read_raw and sf_write_raw.
* src/aiff.c
Fixed default FORMsize in __aiff_open_write ().
* src/sndfile.c
Added copy of filename to internal data structure. IFF/SVX files
contain a NAME header chunk. Both sf_open_read() and sf_open_write()
copy the file name (less the leading path information) to the
filename field.
* src/svx.c
Started implementing writing of files.
1999-08-04 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/svx.c

* src/sndfile.c src/sndfile.h src/raw.c
Further fixing of #includes for MacOS.
1999-07-25 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c src/aiff.c
Added call to ferror () in main header parsing loop of __XXX_open_read
functions. This should fix problems on platforms (MacOS, AmigaOS) where
fseek()ing or fread()ing beyond the end of the file puts the FILE*
stream in an error state until clearerr() is called.
* tests/write_read_test.c
Added tests for RAW header-less PCM files.
* src/common.h
Moved definition of struct tribyte to pcm.c which is the only place
which needs it.
* src/pcm.c
Modified all code which assumed sizeof (struct tribyte) == 3. This code
did not work on MacOS. Thanks to Ben "Jacobs" for pointing this out.
* src/au.c
Removed <sys/stat.h> from list of #includes (not being used).
* src/sndfile.c
Added MacOS specific #ifdef to replace <sys/stat.h>.

to Ben "Jacobs" for supplying these instructions.
1999-07-24 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* configure.in
Removed sndfile.h from generated file list as there were no longer
any autoconf substitutions being made.
* src/raw.c
New file for handling raw header-less PCM files. In order to open these
for read, the user must specify format, pcmbitwidth and channels in the
SF_INFO struct when calling sf_open_read ().
* src/sndfile.c
Added support for raw header-less PCM files.
1999-07-22 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* examples/sfinfo.c
Removed options so the sfinfo program always prints out all the information.
1999-07-19 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/alaw.c
New file for A-law encoding (similar to u-law).

Changed name of adpcm_test.c to lossy_comp_test.c. This test program
will now be used to test Ulaw and Alaw encoding as well as APDCM.
Added tests for Ulaw encoded WAV files.
1999-07-14 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/adpcm_test.c
Initialised amp variable in gen_signal() to remove compiler warning.
1999-07-12 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/aiff.c
In __aiff_open_read () prevented fseek()ing beyond end of file which
was causing trouble on MacOS with the MetroWerks compiler. Thanks to
Ben "Jacobs" for pointing this out.

* src/wav.c
Added fact chunk handling on read and write for all non WAVE_FORMAT_PCM
WAV files.
* src/wav_ima.c
Changed block alignment to be dependant on sample rate. This should make
WAV files created with libsndfile compatible with the MS Windows media
players.
* tests/adpcm_test.c
Reimplemented adpcm_test_short and implemented adpcm_test_int and adpcm_test_double.
Now have full testing of IMA ADPCM WAV file read, write and seek.
1999-06-15 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav_float.c
Fixed function prototype for x86f2d_array () which was causing ocassional
seg. faults on Sparc Solaris machines.

Fixed incorrect calculation of bytespersec header field (IMA ADPCM only).
Fixed bug when writing from int or double data to IMA ADPCM file. Will need
to write test code for this.
Fixed bug in __ima_write () whereby the length of the current block was
calculated incorrectly. Thanks to Jongcheon Park for pointing this out.
1999-03-27 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/*.c
Changed all read/write/lseek function calls to fread/fwrite/
fseek/ftell and added error checking of return values from
fread and fwrite in critical areas of the code.
* src/au.c
Fixed incorrect datasize element in AU header on write.
* tests/error_test.c
Add new test to check all error values have an associated error
string. This will avoid embarrassing real world core dumps.
1999-03-23 Erik de Castro Lopo <erikd AT zip DOT com DOT au>

Filled in missing error strings in SndfileErrors array. Missing entries
can cause core dumps when calling sf_error-str (). Thanks to Sam
<mrsam at-sign geocities.com> for finding this problem.
1999-03-21 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav_ima_adpcm.c
Work on wav_ms_adpcm.c uncovered a bug in __ima_read () when reading
stereo files. Caused by not adjusting offset into buffer of decoded
samples for 2 channels. A similar bug existed in __ima_write ().
Need a test for stereo ADPCM files.
* src/wav_ms_adpcm.c
Decoder working correctly.
1999-03-18 Erik de Castro Lopo <erikd AT zip DOT com DOT au>

before calling __ima_init_block ().
1999-03-17 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c
Started implementing MS ADPCM decoder.
If file is WAVE_FORMAT_ADPCM and length of data chunk is odd, this
encoder seems to add an extra byte. Why not just give an even data
length?
1999-03-16 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/wav.c
Split code out of wav.c to create wav_float.c and wav_ima_adpcm.c.
This will make it easier to add and debug other kinds of WAV files
in future.

Added multiple read test to short_test(), int_test () and
double_test ().
Added extra chunk to all test WAV files to test that reading
stops at end of 'data' chunk.
1999-02-21 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/write_read_test.c
Added tests for little DEC endian AU files.

now work when using these functions.
1999-02-15 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* tests/write_read_test.c:
Force test_buffer array to be double aligned. Sparc Solaris
requires this.
1999-02-14 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/pcm.c:
Fixed a bug which was causing errors in the reading
and writing of 24 bit PCM files.
* doc/api.html
Finished of preliminary documentaion.
1999-02-13 Erik de Castro Lopo <erikd AT zip DOT com DOT au>
* src/aiff.c:
Changed reading of 'COMM' chunk to avoid reading an int
which overlaps an int (4 byte) boundary.
