2000-08-05  Erik de Castro Lopo  <[e-mail]>

    * src/*.[ch]
    Removed double leading underscores from the start of all variable and

    Add checking for and handling of header-less u-law encoded AU/SND files.
    Any file with a ".au" or ".snd" file extension and without the normal
    AU file header is treated as an 8kHz, u-law encoded file.

    New function for opening a headerless u-law encoded file for read.

2000-06-04  Erik de Castro Lopo  <[e-mail]>

    Fixed --enable-justsrc option.

2000-03-07  Erik de Castro Lopo  <[e-mail]>

    Minor changes to allow writing of GSM 6.10 WAV files.

2000-02-28  Erik de Castro Lopo  <[e-mail]>

    * configure.in Makefile.am src/Makefile.am
    Finally got around to figuring out how to build a single library from 
    multiple source directories.
    Reading GSM 6.10 files now seems to work.

2000-01-03  Erik de Castro Lopo  <[e-mail]>

    * src/wav.c
    Added more error reporting in read_fmt_chunk().

1999-12-21  Erik de Castro Lopo  <[e-mail]>

    * examples/sfinfo.c
    Modified program to accept multiple filenames from the command line.

1999-11-27  Erik de Castro Lopo  <[e-mail]>

    * src/wav_ima_adpcm.c
    Moved code around in preparation to adding ability to read/write IMA ADPCM
    encoded AIFF files.

1999-11-16  Erik de Castro Lopo  <[e-mail]>

    * 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  <[e-mail]>

    * src/common.c
    Added string.h to includes. Thanks to Sigbjxrn Skjfret.

    * src/svx.c
    Fixed __svx_close() function to ensure FORM and BODY chunks are correctly
    set.

1999-10-01  Erik de Castro Lopo  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * src/svx.c
    Finished off implementation of write using __psf_hprintf().

1999-09-21  Erik de Castro Lopo  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * src/svx.c
    New file for reading/writing 8SVX and 16SVX files.

    * src/sndfile.[ch] src/common.h
    Changes for SVX files.

    * src/aiff.c
    Fixed header parsing when unknown chunk is found.

1999-08-01  Erik de Castro Lopo  <[e-mail]>

    * src/paf.c
    New file for reading/writing Ensoniq PARIS audio file format.

    * src/sndfile.[ch] src/common.h
    Changes for PAF files.

    * src/sndfile.[ch]
    Added stuff for sf_get_lib_version() function.


1999-07-31  Erik de Castro Lopo  <[e-mail]>

    * src/sndfile.h MacOS/config.h
    Fixed minor MacOS configuration issues.

1999-07-30  Erik de Castro Lopo  <[e-mail]>

    * MacOS/
    Added a new directory for the MacOS config.h file and the
    readme file.

    * src/aiff.c
    Fixed calculation of datalength when reading SSND chunk. Thanks to
    Sigbj鴕n Skj鎟et for pointing out this error.

1999-07-29  Erik de Castro Lopo  <[e-mail]>

    * src/sndfile.c src/sndfile.h src/raw.c
    Further fixing of #includes for MacOS.

1999-07-25  Erik de Castro Lopo  <[e-mail]>

    * 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
