Previously, attempts to read beyond the end of a file would set psf->error
to SFE_SHORT_ERROR. This behaviour diverged from the behaviour of the POSIX
read() call but has now been fixed.
Attempts to read beyond the end of the file will return a short read count
but will not longer set any error.
2002-12-09 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Add more sanity checking when opening a RAW file for read. When format is
not RAW, zero out all members of the SF_INFO struct.

parameter of SEEK_CUR.
* src/file_io.c
Win32's _fstati64() does not work, it returns BS. Re-implemented
psf_get_filelen() in terms of psf_fseek().

* configure.ac
Disable use of native lrint()/lrintf() on Mac OSX. These functions exist on
Mac OSX 10.2 but not on 10.1. Forcing the use of the versions in

10.1.
2002-11-06 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

2002-11-05 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/common.c
In psf_binheader_readf() changed type parameter type "b" type from size_t
to int to prevent errors on IA64 CPU where sizeof (size_t) != sizeof (int).
Thanks to Enrique Robledo Arnuncio for debugging this.
2002-11-04 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* test/command_test.tpl

in src/double64.c.
* src/common.c
Fix all usage of float32_write().
* src/sndfile.h.in
Added SFC_TEST_IEEE_FLOAT_REPLACE command (testing only).

2002-08-23 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* doc/command.html
Fixed typo found by Tommi Ilmonen.
* src/ima_adpcm.c
Changed type of diff from short to int to prevent errors which can occur
during very rare circumstances. Thanks to FUWAFUWA.
2002-08-16 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

2002-08-14 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
Bumped version to 1.0.rc6.
* src/*.c
Modified scaling of normalised floats and doubles to integers. Until now
this has been done by multiplying by 0x8000 for short output, 0x80000000
for 32 bit ints and so on. Unfortunately this can cause an overflow and
wrap around in the target value. All thes values have therefore been
reduced to 0x7FFF, 0x7FFFFFFF and so on. The conversion from ints to
normalised floats and doubles remains unchanged. This does mean that for
repeated conversions normalised float -> pcm16 -> normalised float would
result in a decrease in amplitude of 0x7FFF/0x8000 on every round trip.
This is undesirable but less undesireable than the wrap around I am trying
to avoid.
* tests/floating_point_test.c
Removed file hash checking because new float scaling procedure introduced
above prevented the ability to crate a has on both x86 and PowerPC systems.
2002-08-13 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

* src/common.c
Modified psf_log_printf() to accept the %% conversion specifier to allow
printing of a single '%'.

* src/GSM610/private.h src/GSM610/*.c src/GSM610/Makefile.am
Renamed private.h to gsm610_priv.h to prevent clash with other headers
named private.h in other directories. (Probably only a problem on MacOS 9).
* src/G72x/private.h src/G72x/*.c src/G72x/Makefile.am
Renamed private.h to g72x_priv.h to prevent clash with other headers
named private.h in other directories. (Probably only a problem on MacOS 9).

Changed values of HAVE_LRINT and HAVE_LRINTF to force use of code in
float_cash.h.
* src/sndfile.h
Changes the name of samples field of the SF_INFO to frames. The old name

2002-07-10 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sfendian.[ch]
Changed length count parameters for all endswap_XXX() functions from
sf_count_t (which can be 64 bit even on 32 bit architectures) to int. These
functions are only called frin inside the library, are always called with
integer parameters and doing the actual calculation on 64 bit values is
slow in comparision to doing it on ints.
* examples/sndfile-play.c
More playback hacking for Win32.
2002-07-09 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/common.c

Start adding playback support for Win32.
2002-07-07 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.c
Worked to removed compiler warnings.
Extensive refactoring.
* src/common.[ch]
Added function psf_memset() which works like the standard C function memset
but takes and sf_count_t as the length parameter.
* src/sndfile.c
Replaced calls to memset(0 with calls to psf_memset() as required.
2002-07-06 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Added "libsndfile : " to the start of all error messages. This was suggested
by Conrad Parker author of Sweep ( http://sweep.sourceforge.net/ ).

Further conversion speed ups.
2002-07-03 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/command.c
In major_formats rename "Sphere NIST" to "NIST Sphere".
* src/common.c src/sfendian.c
Moved all endswap_XXX_array() functions to sfendian.c. These functions will
be tweaked to provide maximum performance. Since maximum performance on one
platform does not guarantee maximum performance on another, a small set of
functions will be written and the optimal one chosen at compile time.
* src/common.h src/sfendian.h
Declarations of all endswap_XXX_array() functions moved to sfendian.h.
* src/Makefile.am
Add sfendian.c to build targets.

Removed references to sampltiude RAP format.
* tests/benchmark.tpl
Benchmark program now prints the libsndfile version number when run. This
program was also backported to version 0 to compare results. Version
1.0.0rc2 is faster than version 0.0.28 on most conversions but slower on
some. The slow ones need to be fixed before final release.
2002-06-28 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

2002-06-18 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/utils.c
Fixed an error in error string.
2002-06-17 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* acinclude.m4
Removed exit command to allow cross-compiling.
* Win32/unistd.h src/file_io.c
Moved contents of first file into the second file (enclosed in #ifdef).
Win32/unistd.h is now an empty file but still must be there for libsndfile
to compile on Win32.
* src/sd2.c, src/sndfile.c:
Fixes for Sound Designer II files on big endian systems.
2002-06-16 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
Modified to work around problems with crappy MacOSX version of sed.
Added sanity check for proper values for CFLAGS.
2002-06-14 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Code clean up in sf_open ().
* Win32/Makefile.msvc
Michael Fink's contributed MSVC++ makefile was hacked to bits and put back
together in a new improved form.
* src/file_io.c
Fixes for Win32; _lseeki64() returns an invalid argument for calls like
_lseeki64(fd, 0, SEEK_CUR) so need to use _telli64 (fd) instead.
* src/common.h src/sndfile.c src/wav.c src/aiff.c
Added SFE_LOG_OVERRUN error.
Added termination for potential infinite loop when parsing file headers.
* src/wav.c src/w64.c
Fixed bug casuing incorrect header generation when opening file read/write.
2002-06-12 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* doc/api.html
Improved the documentation to make it clearer that the file read method
and the underlying file format are completely disconnected. Suggested
by Josh Green.
* doc/command.html
Started correcting docs to take into account changes made to the
operations of the sf_command () function. Not complete yet.
* src/sndfile.c
Reverted some changes which had broken the partially working SDII header
parsing. Now have access to an iBook with OS X so reading and writing SDII
files on all platforms should be a reality in the near future. On Mac this
will involve reading the resource fork via the standard MacOS API. To move
a file from Mac to another OS, the resource and data forks will need to be
combined before transfer. The combined file will be read on both Mac and
other OSes like any other file.
2002-06-08 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* ltmain.sh
Applied a patch from http://fink.sourceforge.net/doc/porting/libtool.php
which allows libsndfile to compile on MacOSX 10.1. This patch should not
interfere with compiling on other OSes.
* src/GSM610/private.h
Changes to fix compile problems on MacOSX (see src/GSM610/ChangeLog).
* src/float_cast.h
Added MacOSX replacements for lrint() and lrintf().
2002-06-05 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Replaced the code to print the filename to the log buffer when a file is
opened. This code seems to have been left out during the merge of
sf_open_read() and sf_open_write() to make a single functions sf_open().
2002-06-01 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav.c
Fixed a bug where the WAV header parser was going into an infinite loop
on a badly formed LIST chunk. File supplied by David Viens.
2002-05-25 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
Added a message at the end of the configuration process to warn about the
need for the use of pkg-config when linking programs against version 1 of
libsndfile.
* doc/pkg-config.html
New documentation file containing details of how to use pkg-config to
retrieve settings for CFLAGS and library locations for linking files
against version 1 of libsndfile.
2002-05-17 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav.c
Fixed minor bug in handling of so-called ACIDized WAV files.
2002-05-16 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* Win32/libsndfile.def Win32/Makefile.msvc
Two new files contributed by Michael Fink (from the winLAME project)
which allows libsndfile to be built on windows in a MSDOS box by doing
"nmake -f Makefile.msvc". Way cool!
2002-05-15 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
MacOSX is SSSOOOOOOO screwed up!!! I can't believe how hard it is to
generate a tarball which will configure and compile on that platform.
Joined the libtool mailing list to try and get some answers.
2002-05-13 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
Changed to autoconf version 2.50. MacOSX uses autoconf version 2.53 which
is incompatible with with version 2.13 which had been using until now.
The AC_SYS_LARGE_FILE macro distributed withe autoconf 2.50 is missing a
few features so AC_SYS_EXTRA_LARGE file was defined to replace it.
* configure.in
Changed to automake version 1.5 to try and make a tarball which will
work on MacOSX.
2002-05-12 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav_gsm610.c
Changed name to gsm610.c. Added reading/writing of headerless files.
* src/sndfile.c src/raw.c
Added ability to read/write headerless (SF_FORMAT_RAW) GSM 6.10 files.
2002-05-11 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/lossy_comp_test.c
Clean up in preparation for Autogen-ing this file.
* src/GSM610/*.[ch]
Code cleanup and prepartion forgetting file seek working. Details in
src/GSM610/ChangeLog.
* sndfile.pc.in
Testing complete. Is sndfile.m4 still needed?
2002-05-09 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/write_read_test.tpl tests/rdwr_test.tpl
Merged tests from these two programs into write_read_test.tpl and deleted
rdwr_test.tpl.
2002-05-08 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/w64.c src/svx.c src/paf.c
Fixed bugs in read/write mode.
2002-05-07 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* examples/Makefile.am
Renamed sfplay.c to sndfile-play.c and sndfile_info.c to sndfile-info.c for
consistency when these programs become part of the Debian package
sndfile-programs.
* sndfile.pc.in
New file to replace sndfile-config.in. Libsndfile now uses the pkg-config
model for providing installation parameters to dependant programs.
* src/sndfile.c
Cleanup of code in sf_open().
2002-05-06 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/utils.tpl tests/write_read_test.tpl
More conversion to Autogen fixes and enchancements.
* src/*.c
Read/write mode is now working for 16, 24 and 32 bit PCM as well as 32
bit float and 64 bit double data. More tests still required.
* src/Makefile.am
Added DISTCLEANFILES target to remove config.status and config.last.
* Win32/Makefile.am MacOS/Makefile.am
Added DISTCLEANFILES target to remove Makefile.
2002-05-05 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch] tests/rdwr_test.c
More verifying workings of read/write mode. Fixing bugs found.
* tests/utils.[ch]
Made these files Autogen generated files.
* tests/util.tpl tests/util.def
New Autogen files to generate utils.[ch]. Moved some generic test functions
into this file. Autogen is such a great tool!
2002-05-03 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/pcm.c src/float_cast.h Win32/config.h
Fixed a couple of Win32 specific bugs pointed out by Michael Fink
(maintainer of WinLAME) and David Viens.
* tests/check_log_buffer.[ch] tests/utils.[ch]
Moved check_log_buffer() to utils.[ch] and deleted old file.
2002-05-02 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/common.[ch] src/sndfile.c
New function psf_default_seek() which will be the default seek function
for things like PCM and floating point data. This default is set for
both read and write in sf_open() but can be over-ridden by any codec
during it's initialisation.
2002-05-01 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/au.c
AU files use a data size value of -1 to mean unknown. Fixed au_open_read()
to allow opening files like this.
* tests/rdwr_test .c
Added more tests.
* src/sndfile.c
Fixed bugs in read/write mode found due to improvements in the test
program.
2002-04-30 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/rdwr_test .c
New file for testing read/write mode.
2002-04-29 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* m4/*
Removed all m4 macros from this directory as they get concatenated to form
the file aclocal.m4 anyway.
* sndfile.m4
Moved this from the m4 directory to the root directory asn this is part of
the distribution and is installed during "make install".
2002-04-29 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/float32.c
Removed logging of peaks for all file formats other than AIFF and WAV.
* tests/write_read_test.tpl tests/write_read_test.def
New files which autogen uses to generate write_read_test.c. Doing it this
way makes write_read_test.c far easier to maintain. Other test programs
will be converted to autogen in the near future.
* src/*.c
Fixed a few bugs found when testing on Sparc (bug endian) Solaris.
2002-04-28 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

Fixed a bug in the routines which search for Large File Support on systems
which have large file support by defualt.
2002-04-27 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch]
Found and fixed an issue which can cause a bug in other software (I was
porting Conrad Parker's Sweep program from version 0 of the library to
version 1). When opening a file for write, the libsndfile code would
set the sfinfo.samples field to a maximum value.
* tests/write_read_test.c
Added tests to detect the above problem.
2002-04-25 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch]
Finished base implementation of read/write mode. Much more testing still
needed.
* m4/largefile.m4
Macro for detecting Large File Standard capabilities. This macro was ripped
out of the aclocal.m4 file of GNU tar-1.13.
* configure.in
Added detection of large file support. Files larger than 2 Gigabytes should
now be supported on 64 bit platforms and many 32 bit platforms including
Linux (2.4 kernel, glibc-2.2), *BSD, MacOS, Win32.
* libsndfile_convert_version.py
A Python script which attempts to autoconvert code written to use version 0
to version 1.
2002-04-24 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch]
Finished base implementation of read/write mode. Much more testing still
needed.
* tests/write_read_test.c
Preliminary tests for read/write mode added. More needed.
2002-04-20 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.[ch]
Removed sf_open_read() and sf_open_write() functions,replacting them with
sf_open() which takes an extra mode parameter (SF_OPEN_READ, SF_OPEN_WRITE,
or SF_OPEN_RDWR). This new function sf_open can now be modified to allow
opening a file formodification (RDWR).
2002-04-19 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.c
Completed merging of separate xxx_open_read() and xxx_open_write()
functions. All tests pass.
2002-04-18 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/au.c
Massive refactoring required to merge au_open_read() with au_open_write()
to create au_open().
2002-04-17 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.c
Started changes required to allow a sound file to be opened in read/write
mode, with separate file pointers for read and write. This involves merging
of encoder/decoder functions like pcm_read_init() and pcm_write_init()
int a new function pcm_init() as well as doing something similar for all
the file type specific functions ie aiff_open_read() and aiff_open_write()
were merged to make the function aiff_open().
2002-04-15 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/file_io.c
New file containing psf_fopen(), psf_fread(), psf_fwrite(), psf_fseek() and
psf_ftell() functions. These function will replace use of fopen/fread/fwrite
etc and allow access to files larger than 2 gigabytes on a number of 32 bit
OSes (Linux on x86, 32 bit Solaris user space apps, Win32 and MacOS).
* src/*.c
Replaced all instances of fopen with psf_open, fread with psd_read, fwrite
with psf_write and so on.
2002-03-11 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/dwvw.c
Finally fixed all known problems with 12, 16 and 24 bit DWVW encoding.
* tests/floating_point_test.c
Added tests for 12, 16 and 24 bit DWVW encoding.
2002-03-03 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* m4/endian.m4
Defines a new m4 macro AC_C_FIND_ENDIAN, for determining the endian-ness of
the target CPU. It first checks for the definition of BYTE_ORDER in
<endian.h>, then in <sys/types.h> and <sys/param.h>. If none of these work
and the C compiler is not a cross compiler it compiles and runs a program
to test for endian-ness. If the compiler is a cross compiler it makes a
guess based on $target_cpu.
* configure.in
Modified to use AC_C_FIND_ENDIAN.
* src/sfendian.h
Simplified.
2002-02-23 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/floating_point_test.c
Tests completely rewritten using the dft_cmp function. Now able to
calculate a quick guesstimate of the Signal to Noise Ratio of the encoder.

* tests/dft_cmp.[ch]
New files containing functions for comparing pre and post lossily
compressed data using a quickly hacked DFT.
* tests/utils.[ch]
New files containing functions for saving pre and post encoded data in a
file readable by the GNU Octave package.
2002-02-13 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* m4/lrint.m4 m4/lrintf.m4
Fixed m4 macros to define HAVE_LRINT and HAVE_LRINTF even when the test
is cached.
2002-02-12 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/floating_point_test.c
Fixed improper use of strncat ().
2002-02-11 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/headerless_test.c
New test program to test the ability to open and read a known file type as a
RAW header-less file.
2002-02-07 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/losy_comp_test.c
Added a test to ensure that the data read from a file is not all zeros.
* examples/sfconvert.c
Added "-gsm610" encoding types.
2002-01-29 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

* src/aiff.c
Improved reporting of encoding types.
* src/voc.c
Clean up.
2002-01-27 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/dwvw.c
New file implementing lossless Delta Word Variable Width (DWVW) encoding.
Reading 12 bit DWVW is now working.
* src/aiff.c common.h sndfile.c
Added hooks for DWVW encoded AIFF and RAW files.
2002-01-15 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/w64.c
Robustify header parsing.
* src/wav_w64.h
Header file wav.h was renamed to wav_w64.h to signify sharing of
definitions across the two file types.
* src/wav.c src/w64.c src/wav_w64.c
Refactoring.
Modified and moved functions with a high degree of similarity between
wav.c and w64.c to wav_w64.c.
2002-01-14 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/w64.c
Completed work on getting read and write working.

Added tests for W64 files.
2002-01-13 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.c
Modded all code in file header writing routines to use
psf_new_binheader_writef().
Removed psf_binheader_writef() from src/common.c.
Globally replaced psf_new_binheader_writef with psf_binheader_writef.
2002-01-12 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.c
Modded all code in file parsing routines to use psf_new_binheader_readf().
Removed psf_binheader_readf() from src/common.c.
Globally replaced psf_new_binheader_readf with psf_binheader_readf.
* src/common.[ch]
Added new function psf_new_binheader_writef () which will soon replace
psf_binheader_writef (). The new function has basically the same function
as the original but has a more flexible and capable interface. It also
allows the writing of 64 bit integer values for files contains 64 bit file
offsets.
2002-01-11 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/formats.c src/sndfile.c src/sndfile.h
Added code allowing full enumeration of supported file formats via the
sf_command () interface.
This feature will allow applications to avoid needing recompilation when
support for new file formats are added to libsndfile.
* tests/command_test.c
Added test code for the above feature.
* examples/list_formats.c
New file. An example of the use of the supported file enumeration
interface. This program lists all the major formats and for each major
format the supported subformats.
2002-01-10 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch] tests/*.c
Changed command parameter of sf_command () function from a test string to
an int. The valid values for the command parameter begin with SFC_ and are
listed in src/sndfile.h.
2001-12-20 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/formats.c src/sndfile.c
Added an way of enumerating a set of common file formats using the
sf_command () interface. This interface was suggested by Dominic Mazzoni,
one of the main authors of Audacity (http://audacity.sourceforge.net/).
2001-12-26 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Added checking of filename parameter in sf_open_read (). Previousy, if a
NULL pointer was passed the library would segfault.
2001-12-18 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/common.c src/common.h
Changed the len parameter of the endswap_*_array () functions from type
int to type long.
* src/pcm.c
Fixed a problem which
2001-12-15 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c
Added conditional #include <sys/types.h> for EMX/gcc on OS/2. Thanks to
Paul Hartman for pointing this out.
* tests/lossy_comp_test.c tests/floating_point_test.c
Added definitions for M_PI for when it isn't defined in <math.h>.
2001-11-30 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/ircam.c
Re-implemented the header reader. Old version was making incorrect
assumptions about the endian-ness of the file from the magic number at the
start of the file. The new code looks at the integer which holds the
number of channels and determines the endian-ness from that.
2001-11-30 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/aiff.c
Added support for other AIFC types ('raw ', 'in32', '23ni').
Further work on IMA ADPCM encoding.
2001-11-29 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/ima_adpcm.c
Renamed from wav_ima_adpcm.c. This file will soon handle IMA ADPCM
encodings for both WAV and AIFF files.
* src/aiff.c
Started adding IMA ADPCM support.
2001-11-28 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/double.c
New file for handling double precision floating point (SF_FORMAT_DOUBLE)
data.
* src/wav.c src/aiff.c src/au.c src/raw.c
Added support for SF_FORMAT_DOUBLE data.
* src/common.[ch]
Addition of endswap_long_array () for endian swapping 64 bit integers. This
function will work correctly on processors with 32 bit and 64 bit longs.
Optimised endswap_short_array () and endswap_int_array ().
* tests/pcm_test.c
Added and extra check. After the first file of each type is written to disk
a checksum is performed of the first 64 bytes and checked against a pre-
calculated value. This will work whatever the endian-ness of the host
machine.
2001-11-27 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/aiff.c
Added handling of u-law, A-law encoded AIFF files. Thanks to Tom Erbe for
supplying example files.
* tests/lossy_comp_test.c
Added tests for above.
* src/common.h src/*.c
Removed function typedefs from common.h and function pointer casting in all
the other files. This allows the compiler to perform proper type checking.
Hopefully this will prevernt problems like the sf_seek bug for OpenBSD,
BeOS etc.
* src/common.[ch]
Added new function psf_new_binheader_readf () which will eventually replace
psf_binheader_readf (). The new function has basically the same function as
the original but has a more flexible and capable interface. It also allows
the reading of 64 bit integer values for files contains 64 bit file
offsets.
2001-11-26 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/voc.c
Completed implementation of VOC file handling. Can now handle 8 and 16 bit
PCM, u-law and A-law files with one or two channels.
* src/write_read_test.c tests/lossy_comp_test.c
Added tests for VOC files.
2001-11-22 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/float_cast.h
Added inline asm version of lrint/lrintf for MacOS. Solution provided by
Stephane Letz.
* src/voc.c
More work on this braindamaged format. The VOC files produced by SoX also
have a number of inconsistencies.
2001-11-19 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/paf.c
Added support for 8 bit PCM PAF files.
* tests/write_read_test.c
Added tests for 8 bit PAF files.
2001-11-18 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/pcm_test.c
New test program to test for correct scaling of integer values between
different sized integer containers (ie short -> int).
The new specs for libsndfile state that when the source and destination
containers are of a different size, the most significant bit of the source
value becomes the most significant bit of the destination container.
* src/pcm.c src/paf.c
Modified to pass the above test program.
* tests/write_read_test.c tests/lossy_comp_test.c
Modified to work with the new scaling rules.
2001-11-17 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/raw.c tests/write_read_test.c tests/write_read_test.c
Added ability to do raw reads/writes of float, u-law and A-law files.
* src/*.[ch] examples/*.[ch] tests/*.[ch]
Removed dependance on pcmbitwidth field of SF_INFO struct and moved to new
SF_FORMAT_* types and use of SF_ENDIAN_BIG/LITTLE/CPU.
2001-11-12 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/*.[ch]
Started implmentation of major changes documented in doc/version1.html.
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).
--------------------------------------------------------------------------------
This is the boundary between version 1 of the library above and version 0 below.
--------------------------------------------------------------------------------
2001-11-11 Erik de Castro Lopo <erikd AT zipworld 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.
2001-11-10 Erik de Castro Lopo <erikd AT zipworld 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.
2001-11-09 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/pcm.c
Fixed problem with normalisation code where a value of 1.0 could map to
a value greater than MAX_SHORT or MAX_INT. Thanks to Roger Dannenberg for
pointing this out.
2001-11-08 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/pcm.c
Fixed scaling issue when reading/writing 8 bit files using
sf_read/sf_write_short ().
On read, values are scaled so that the most significant bit in the char
ends up in the most significant bit of the short. On write, values are
scaled so that most significant bit in the short ends up as the most
significant bit in the char.
2001-11-07 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/au.c src/sndfile.c
Added support for 32 bit float data in big and little endian AU files.
* tests/write_read_test.c
Added tests for 32 bit float data in AU files.
2001-11-06 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* tests/lossy_comp_test.c
Finalised testing of stereo files where possible.
2001-11-05 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav_ms_adpcm.c
Fixed bug in writing stereo MS ADPCM WAV files. Thanks to Xu Xin for
pointing out this problem.
2001-10-24 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav_ms_adpcm.c
Modified function srate2blocksize () to handle 44k1Hz stereo files.
2001-10-21 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/w64.c
Added support for Sonic Foundry 64 bit WAV format. As Linux (my main
development platform) does not yet support 64 bit file offsets by default,
current handling of this file format treats everything as 32 bit and fails
openning the file, if it finds anything that goes beyond 32 bit values.
* src/sndfile.[hc] src/common.h src/Makefile.am
Added hooks for W64 support.
2001-10-21 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* configure.in
Added more warnings options to CFLAGS when the gcc compiler is detected.
* src/*.[ch] tests/*.c examples/*.c
Started fixing the warning messages due to the new CFLASG.
* src/voc.c
More work on VOC file read/writing.
* src/paf.c
Found that PAF files were not checking the normalisation flag when reading
or writing floats and doubles. Fixed it.
* tests/floating_point_test.c
Added specific test for the above problem.
* src/float_cast.h src/pcm.c
Added a section for Win32 to define lrint () and lrintf () in the header
and implement it in the pcm.c
2001-10-20 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* sndfile-config.in m4/sndfile.m4
These files were donated by Conrad Parker who also provided instructions
on how to install them using autoconf/automake.
* src/float_cast.h
Fiddled around with this file some more. On Linux and other gcc supported
OSes use the C99 functions lrintf() and lrint() for casting from floating
point to int without incurring the huge perfromance penalty (particularly
on the i386 family) caused by the regular C cast from float to int.
These new C99 functions replace the FLOAT_TO_* and DOUBLE_TO_* macros which
I had been playing with.
* configure.in m4/lrint.m4 m4/lrintf.m4
Add detection of these functions.
2001-10-17 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/voc.c
Completed code for reading VOC files containing a single audio data
segment.
Started implementing code to handle files with multiple VOC_SOUND_DATA
segments but couldn't be bothered finishing it. Multiple segment files can
have different sample rates for different sections and other nasties like
silence and repeat segments.
2001-10-16 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/common.h src/*.c
Removed SF_PRIVATE struct field fdata and replaced it with extra_data.
* src/voc.c
Further development of the read part of this woefult file format.
2001-10-04 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/float_cast.h
Implemented gcc and i386 floating point to int cast macros. Standard cast
will be used when not on gcc for i385.
* src/pcm.c
Modified all uses of FLOAT/DOUBLE_TO_INT and FLOAT/DOUBLE_TO_SHORT casts to
comply with macros in float_cast.h.
2001-10-04 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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 zipworld DOT com DOT au>
* src/ircam.c
New file to handle Berkeley/IRCAM/CARL files.

Modified for IRCAM handling.
* tests/*.c
Added tests for IRCAM files.
2001-09-27 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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 zipworld DOT com DOT au>
* tests/stdio_test.sh tests/stdout_test.c tests/stdin_test.c
New test programs to verify the correct operation of reading from stdin and
writing to stdout.
* src/sndfile.c wav.c au.c nist.c paf.c
Fixed a bugs uncovered by the new test programs above.
2001-09-15 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/sndfile.c wav.c
Fixed a bug preventing reading a file from stdin. Found by T. Narita.
2001-09-12 Erik de Castro Lopo <erikd AT zipworld 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 zipworld DOT com DOT au>
* src/sndfile.c
Implemented sf_command ("norm float").
* src/*.c
Implemented handling of sf_command ("set-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 zipworld 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/float_cast.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 zipworld 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.

2001-08-11 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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 zipworld 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 zipworld 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 zipworld DOT com DOT au>
* tests/read_seek_test.c tests/lossy_comp_test.c

file data.
2001-07-20 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/paf.c src/wav_gsm610.c
Removed two printf()s which had escaped notice for some time (thanks
Sigbjørn Skjæret).
2001-07-19 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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 zipworld 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 zipworld 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 zipworld 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 zipworld DOT com DOT au>
* src/wav.c
Fixed endian bug when reading PEAK chunk on big endian machines.

general.
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 zipworld DOT com DOT au>

Added handling of PEAK chunks on file read.
2001-05-31 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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.

Added calls to check_log_buffer () after each call to sf_open_XXX ().
2001-05-29 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav.c src/wav_ms_adpcm.c src/wav_gsm610.c
Major rehack of header writing using psf_binheader_writef ().
2001-05-28 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav.c src/wav_ima_adpcm.c
Major rehack of header writing using psf_binheader_writef ().

* src/wav.c
Changed return type of get_encoding_str () to prevent compiler warnings on
Mac OSX.
* src/aiff.c src/au.c
Major rehack of header writing using psf_binheader_writef ().
2001-05-25 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

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 zipworld 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.
2001-05-23 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

Reading GSM 6.10 files now seems to work.
2000-01-03 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/wav.c
Added more error reporting in read_fmt_chunk().
1999-12-21 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>

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 zipworld 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 zipworld 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 zipworld 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 zipworld DOT com DOT au>
* src/svx.c
Finished off implementation of write using __psf_hprintf().
1999-09-21 Erik de Castro Lopo <erikd AT zipworld 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 zipworld 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 zipworld DOT com DOT au>

* src/sndfile.c src/sndfile.h src/raw.c
Further fixing of #includes for MacOS.
1999-07-25 Erik de Castro Lopo <erikd AT zipworld 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>.

* 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 zipworld 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 zipworld DOT com DOT au>
* src/alaw.c
New file for A-law encoding (similar to u-law).

1999-07-12 Erik de Castro Lopo <erikd AT zipworld 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

* src/wav.c
Added fact chunk handling on read and write for all non WAVE_FORMAT_PCM
WAV files.

Changed block alignment to be dependant on sample rate. This should make
WAV files created with libsndfile compatible with the MS Windows media
players.

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 zipworld DOT com DOT au>

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 zipworld 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 zipworld DOT com DOT au>

<mrsam at-sign geocities.com> for finding this problem.
1999-03-21 Erik de Castro Lopo <erikd AT zipworld 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.

before calling __ima_init_block ().
1999-03-17 Erik de Castro Lopo <erikd AT zipworld 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 zipworld DOT com DOT au>
* src/wav.c
Split code out of wav.c to create wav_float.c and wav_ima_adpcm.c.

Finished of preliminary documentaion.
1999-02-13 Erik de Castro Lopo <erikd AT zipworld DOT com DOT au>
* src/aiff.c:
Changed reading of 'COMM' chunk to avoid reading an int
which overlaps an int (4 byte) boundary.
