pointing this out.
1999-09-24 Erik de Castro Lopo <erikd@zip.com.au>
* src/paf.c
Fixed a bug with reading and writing 24 bit stereo PAF files. This problem

in terms of frames rather than items.
1999-09-23 Erik de Castro Lopo <erikd@zip.com.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@zip.com.au>
* src/svx.c
Finished off implementation of write using __psf_hprintf().
1999-09-21 Erik de Castro Lopo <erikd@zip.com.au>
* src/common.h

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@zip.com.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@zip.com.au>
* src/svx.c

Further fixing of #includes for MacOS.
1999-07-25 Erik de Castro Lopo <erikd@zip.com.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@zip.com.au>
* examples/sfinfo.c
Removed options so the sfinfo program always prints out all the information.
1999-07-19 Erik de Castro Lopo <erikd@zip.com.au>
* src/alaw.c
New file for A-law encoding (similar to u-law).

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@zip.com.au>

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

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@zip.com.au>
* tests/write_read_test.c
Added tests for little DEC endian AU files.

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