2003-12-17  Michael Pruett <michael@68k.org>

        Fix two bugs related to processing 24-bit audio data.

        * libaudiofile/data.c: Fix calculation of bytes per virtual frame
        in the case of 24-bit audio data.  Previously, requesting more
        than _AF_ATOMIC_NVFRAMES from afReadFrames when reading a 24-bit
        audio file would result in corrupted audio data since the audio
        data pointer would be incremented using a sample size of 3 bytes
        rather than 4 bytes.

        * libaudiofile/openclose.c: Set virtual sample width by default to
        the same value as file sample width.  Previously for 24-bit audio
        data, the virtual sample width would be incorrectly set to 32.

        * test/twentyfour2.c: Add new test which checks reading and
        writing a large amount of 24-bit audio data.  This program
        serves as a regression test for a bug in the Audio File Library
        in which requesting more than 1024 frames (_AF_ATOMIC_NVFRAMES)
        from afReadFrames when reading a 24-bit audio file would result
        in corrupted audio data.

2003-12-08  Michael Pruett <michael@68k.org>

        * examples/*, test/*: Add examples subdirectory. Separate
        example programs from regression test programs. Remove obsolete
        test programs.

2003-12-03  Michael Pruett <michael@68k.org>

        * sfcommands/sfconvert.c: Fix argument parsing in sfconvert.
        * sfcommands/printinfo.c: Fix format strings to handle different
        sizes of off_t when printing track byte count, data offset,
        and frame count.

2003-10-01  Michael Pruett <michael@68k.org>

        * sfcommands/printinfo.c: Change printfileinfo to display duration
        with millisecond accuracy.

2003-09-29  Michael Pruett <michael@68k.org>

        * test/seek.c: Include <string.h> for memcmp.  Thanks to Christian
        Weisgerber for catching this omission.

        raw audio data files.

2002-05-17  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/wave.c: Add support for reading names of markers
        in WAVE files.  Locations of WAVE markers are now assumed to be
        in units of frames as is the case with Sound Forge.
        * libaudiofile/wavewrite.c, libaudiofile/wave.h: Add support
        for writing markers in WAVE files.

        Thanks to Davy Durham for the above patches.

2002-03-24  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/marker.c: afInitMarkerComment was corrupting the
        marker's name because it would free and allocate the marker's
        name but write to its comment.  Thanks to Daniel Kobras and
        Davy Durham for noticing and fixing this problem.

2002-02-20  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/*: Eliminate unnecessary global symbols.  Thanks

        * libaudiofile/openclose.c: Applied Chris Wolf's patch invoking
        the macro SETBINARYMODE on all file pointers before handing
        them off to the AF VFS.  This macro does nothing on non-Windows
        systems.

2001-08-27  Michael Pruett <mpruett@sgi.com>

        * win32/*: Added Chris Wolf's Windows port of the Audio File Library.

        * libaudiofile/afinternal.h: Declared new internal tokens for
        compression parameters in PV lists.

        * libaudiofile/audiofile.h: Declared constants for DV and MS
        ADPCM compression formats.

        * libaudiofile/wave.[ch]: Handle IMA and MS ADPCM compression

        * Released version 0.2.2 of the Audio File Library.

2001-07-19  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/format.c: Add afSetChannelMatrix and
        afGetVirtualChannels.

        * libaudiofile/openclose.c: Add afIdentifyFD, afIdentifyNamedFD,
        afOpenFD, and afOpenNamedFD.

2001-07-18  Michael Pruett <mpruett@sgi.com>

        * sfcommands/sfconvert.c: Use a fixed-size buffer for reading
        and writing audio data, thus reducing memory usage when
        converting large sound files.  Add float, integer, and channels
        keywords to sfconvert.

        * docs/sfconvert: Updated documentation to reflect new
        keywords.

        * libaudiofile/setup.c: Change the default file format for

        constants.

2001-06-28  Mark Murnane <mark.murnane@sun.com>

        * libaudiofile/{openclose.c,track.c}: Included string.h to
        ensure proper declaration of memset().

2001-06-19  Michael Pruett <mpruett@sgi.com>

        * test/power.c: Adding a new example program which calculates
        the power and peak amplitudes of an audio file.  This program
        is based on Chris Vaill's normalize.

2001-06-06  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/modules.c: Fix conversion between 24-bit and
        32-bit data formats on little-endian systems.  Thanks to Axel
        Roebel for pointing out this problem.

        * libaudiofile/aiffwrite.c:  Don't write a MARK chunk unless
        markers are present.  Don't confuse the big-endian marker id
        used for writing to the file with its native-endian value used
        in calls to afGetMark*.

        * test/twentyfour.c: Add a new program to test the conversion
        between 24-bit signed integer data in a file and 32-bit signed

2001-06-05  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/af_vfs.c: Prevent division by zero in af_fread
        and af_fwrite when size is zero.

        * libaudiofile/aiff.c: Check that the number of markers in a
        MARK chunk is positive before allocating markers.

        Thanks to Axel Roebel for pointing out both of these problems.

2001-05-19  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/nist.[ch]: Checked in support for recognizing
        NIST SPHERE files.

2001-05-16  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/query.c: Backing out last change.  The file
        format and instrument parameter selectors once again return
        arrays of type 'int' rather than arrays of type 'long'.

        Although the AUpv structure uses only long integers, the Audio
        File Library's API uses 'int' and not 'long' when describing
        file formats and instrument parameters.  Furthermore all
        existing applications expect the affected query calls to return
        arrays of int.

        * test/query2.c: Expect arrays of int rather than arrays of
        long when querying on file formats and instrument parameters.

2001-05-09  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/aiffwrite.c: Fix a memory leak in WriteMARK, and
        make WriteMARK use the afGetMark* calls rather than accessing
        track->markers directly.

        * libaudiofile/util.[ch]: Add _af_print_pvlist for debugging.

2001-05-04  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/ircam.[ch]: Make a first pass at supporting the
        IRCAM file format.

2001-04-25  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/query.c: Although the documentation states that
        certain selectors return an array of integers, the AUpv structure
        uses only long integers.  I'm resolving the ambiguity in the
        documentation by making such selectors return an array of long
        integers.

        This change has no impact on platforms where sizeof (int) ==
        sizeof (long), but it makes the query system consistent on
        platforms where the above is not the case.

2001-04-23  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/wavewrite.c: Fixed a bug seen on 64-bit systems
        in which WAVE files would be created with zero-length RIFF and
        data chunks.  (Thanks to Wayne Price for bringing this bug to
        my attention.)

2001-04-19  Michael Pruett <mpruett@sgi.com>

        * sfcommands/sfconvert.c: Make sfconvert use the sample rate of
        the input file.

2001-04-09  Michael Pruett <mpruett@sgi.com>

        * Include <string.h> in source files which use string functions.
        (Thanks to Michael Madore for pointing out this omission.)
        * Fix calculation of file position for G.711 compression.
        (Thanks to Bruce Forsberg for pointing out this bug.)
        * configure.in: Check for int{8,16,32}_t and define them
        appropriately if they are missing.

2001-02-20  Michael Pruett <mpruett@sgi.com>

        * Released version 0.2.1.
        * Removed -release flag on library build.
        * libaudiofile/*: Added some lint-style comments to clean up
        some warnings pointed out by Jean-Francois Panisset.

2000-12-15  Michael Pruett <mpruett@sgi.com>

        * Released version 0.2.

2000-11-01  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/*: Finished integrating the modules code.

2000-10-26  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/raw.[ch]: Added support for raw file reading and
        writing.

2000-10-24  Michael Pruett <mpruett@sgi.com>

        * libaudiofile/*: Cleaned up the Audio File Library and improved
        error handling.

2000-10-09  Michael Pruett <michael@68k.org>

        * libaudiofile/wave*.[ch]: WAVE format chunks can occur in any
        order.  Processing of WAVE chunks now acts accordingly.
        (Thanks to Michael Krause for pointing out shortcomings in the
        previous implementation.)
        * libaudiofile/*.[ch]: The VFS layer doesn't handle SEEK_END
        as a valid mode for fseek; we must use af_flength instead.
        * Removed query from the test suite as it did not handle
        values of AU_NULL_PVLIST returned from afQuery.  (It even
        crashes under IRIX.)

2000-10-04  Michael Pruett <michael@68k.org>

        * libaudiofile/*.c: Added better error handling.
        * libaudiofile/*.c: Added the file format unit structure,
        updated querying accordingly.  All queries except compression
        types are implemented.
        * Added query and query2 to the test suite.

2000-09-13  Michael Pruett <michael@68k.org>

        * libaudiofile/*.c: Added support for G.711 a-law, thanks to
        Bruce Forsberg.

1999-11-20  Michael Pruett <michael@68k.org>

        * libaudiofile/*.c: Cleaning up, added afOpenFD.

1999-08-21  Kjartan Maraas  <kmaraas@online.no>

        * */*c: Even more warning fixes - initialize vars, add 'int' as return
        type of a function, and include headers.
        
1999-08-20 Elliot Lee <sopwith@redhat.com>
        * */*.c: More warning fixes - remove unused variables, add 'int' as return type
        of main(), and include some more header files.

1999-08-18 Anders Carlsson  <anders.carlsson@tordata.se>

        * Fixed compiler warnings.

1999-08-16 Elliot Lee <sopwith@redhat.com>
        * libaudiofile/af_vfs.[ch]: Virtualize file access.
        * libaudiofile/*.[ch]: Use the new virtualized file access routines.

1999-05-09  Michael Pruett  <michael@68k.org>

        * bread.c, ulaw.c: If more sample frames are requested than
        remain in the file, limit the number of sample frames that can
        be returned.  This bug was brought to my attention by Scott
        Heavner.
        * test/sgi.[ch]: These files contain SGI Audio Library routines
        used in SGI-specific test programs.
        * test/irixread.c, test/irixtest.c, test/irixtestloop.c: These
        programs now use the routines contained in sgi.[ch] and are more
        robust.

1999-05-23  Raja R Harinath  <harinath@cs.umn.edu>

        * test/miscread.c: Include <config.h>.
        * test/miscwrite.c: Likewise.
        * test/writeaiff.c: Likewise.
        * test/writenext.c: Likewise.
        * test/writeulaw.c: Likewise.
        * test/writewave.c: Likewise.
          
1999-05-09  Michael Pruett  <michael@68k.org>

        * Merge in Audio File Library version 0.1.7.

        * aiff.c: Fixed an obscure bug in AIFF parsing in the
        instrument chunk parsing code.  Made AIFF parsing slightly
        cleaner by replacing multiple-character constant comparisons
        with memcmp and strings.

        * compression.[ch]: Added support for compressed audio.

        * au.c, auwrite.c, ulaw.c, g711.[ch]: Incorporated support for
        G.711 mu-law encoding.  Currently this encoding is only available
        for NeXT/Sun .snd/.au format files.

        * audiofile.c: Virtual byte order is now set properly.

        * aiff.c, audiofile.c, auwrite.c, bread.c, bwrite.c,
        compression.c, instrument.c, loop.c, marker.c, misc.c,
        query.c, ulaw.c: Added more error checking.

        * docs/*: Documentation has been improved.

        * test/*: Several simple test programs have been added as a
        test suite.

        * sfcommands/*: Fix hard-coded virtual byte order since it's
        now set by the library.

        * configure.in: Fixed platform-specific tests and detect byte
        order at configuration time.

1999-04-11  James Henstridge  <james@daa.com.au>

        * audiofile.spec.in: added %{prefix}/share/aclocal/* to files
        list for the devel package.

1999-02-24  Martin Baulig  <martin@home-of-linux.org>

        * configure.in (BUILD_STATIC_LIBS): New automake conditional.

        * sfcommands/Makefile.am, test/Makefile.am: Only link statically
        if we build static libraries.

1999-02-22  Raja R Harinath  <harinath@cs.umn.edu>

        * libaudiofile/audiofile.h (extern "C"): Remove duplicated
        __cplusplus guards.

1999-02-22  Michael Fulbright <drmike@redhat.com>
        * Fixed spec file to be autogenerated

1999-02-22  Michael Pruett  <michael@68k.org>
            Elliot Lee  <sopwith@redhat.com>

        * */*: Merge in audiofile 0.1.6.
        
1999-01-20  Jeff Garzik  <jgarzik@pobox.com>

        * libaudiofile/wave.c:
        Fix newly-uncovered bug caught by Mike Bond <mike.bond@template.com>.

1999-01-17  Jeff Garzik  <jgarzik@pobox.com>

        * aiff.c, wave.c:
        Replaced some [int == '1234'] comparisons with memcmp.

        * aiff.h:
        Replaced large enum value with 'const unsigned long' instead, to
        silence ANSI C compiler warning.

        * ulaw.c:
        Converted function declarations from K&R to ANSI C, silencing a
        (big surprise) ANSI C compiler warning.

        * libaudiofile/Makefile.am:
        Remove non-existent instrument.h, loop.h, marker.h

        * sfcommands/Makefile.am:
        Add README to EXTRA_DIST.

        * libaudiofile/aiff.c, libaudiofile/aiffwrite.c,
          libaudiofile/audiofile.c, libaudiofile/auwrite.c,
          libaudiofile/bread.c, libaudiofile/bwrite.c,

          libaudiofile/swapblock.c, libaudiofile/swapblock.h,
          libaudiofile/ulaw.c, libaudiofile/ulaw.h:
        More namespace cleanups.  Made a few functions static, several
        more renamed to add "_af_" prefix.

        * libaudiofile/instrument.h, libaudiofile/loop.h,
          libaudiofile/marker.h:
        Removed because they only contained prototypes of static funcs,
        and were included only by their implementation modules.

1999-01-16  Jeff Garzik  <jgarzik@pobox.com>

        * test/transparency.c:
        Change to unsigned short to avoid Sun CC warning.

        * libaudiofile/swapblock.c:
        Changed const long to a #define, Sun CC choked on the const.
        The definition of u_int16_t may be interfering with array
        definitions like this one, b/c u_int16_t is a macro instead of a
        typedef on Solaris platforms.

        * acconfig.h:
        Protected against multiple inclusion, using @TOP@ and @BOTTOM@.

        * libaudiofile/afinternal.h:
        Include config.h for u_int8_t and friends.

        * libaudiofile/audiofile.h, libaudiofile/aupvlist.h:
        Mark as extern 'c' if C++ compile.

        Major namespace cleanups:
        Made several functions static as warranted.
        Renamed a some exported private functions to _af_funcname
        to prevent collision.

1999-01-16  Jeff Garzik  <jgarzik@pobox.com>

        * autogen.sh configure.in acconfig.h:
        Added AM_CONFIG_HEADER and requisite support for it.

        Conditionally include config.h.

1999-01-16  Raja R Harinath  <harinath@cs.umn.edu>

        * libaudiofile/error.c (afSetErrorHandler): Provide a better
        implementation which agrees with the semantics of the variable
        names, and usual "set_error_handler" type of functions.  (Modifies
        a "fix" in commit: "1999-01-16  Jeff Garzik  <jgarzik@pobox.com>").

1999-01-16  Jeff Garzik  <jgarzik@pobox.com>

        * libaudiofile/aes.c, libaudiofile/aiff.c, libaudiofile/aiffwrite.c,
          libaudiofile/au.c, libaudiofile/audiofile.c, libaudiofile/aupv.c,

          libaudiofile/wavewrite.c, sfcommands/printinfo.c,
          sfcommands/sfconvert.c, sfcommands/sfinfo.c:
        Corrected missing-default-case, unused-var, no-return-value,
        implicit-declaration, other gcc warnings.  Fixing those warnings
        also fixed many bugs.

        * test/adddcoffset.c, test/copy.c, test/linuxtest.c, test/miscread.c,
          test/miscwrite.c, test/results.c, test/transparency.c:
        Changed main() declaration to standard one, fixed warnings.

1998-12-10  Jeff Garzik  <jgarzik@pobox.com>

        * tests/miscwrite.c:
        include string.h to silence warning about strlen

Tue Dec  8 21:38:08 PST 1998 Manish Singh <yosh@gimp.org>

        * auto* fixes for make dist

1998-12-07  Jeff Garzik  <jgarzik@pobox.com>

        * LICENSE:
        Removed.  Automake automatically adds the file COPYING to the
        distribution, so this file is redundant.

1998-12-01  Yo Ric Dude  <ricdude@ix.netcom.com>

        * libaudiofile/Makefile.am, au.c, audiofile.c, audiofile.h,
        bread.c, teach libaudiofile how to handle u-law encoded .au
        files. NOTE: only added routines for reading files.

        * libaudiofile/ulaw.c, libaudiofile/ulaw.h: u-law algorithms from 
        http://www.itl.atr.co.jp/comp.speech/Section2/Q2.7.html.

1998-10-21 Bertrand Guiheneuf <Bertrand.Guiheneuf@inria.fr>
        * added an audiofile-config and an audiofile.m4
        
1998-10-17  Raja R Harinath  <harinath@cs.umn.edu>

        * configure.in (u_int_{8,16,32}_t): Define these to some "natural"
        C types if the typedefs are missing.

        * libaudiofile/Makefile.am (include_HEADERS): 
        Remove spurious empty line.

Wed Oct  7 02:13:34 PDT 1998 Manish Singh <yosh@gimp.org>

        * auto* stuff fixes

Wed Oct  7 02:08:30 CDT 1998   Frank Belew   <frb@umr.edu>
        
        * added support for automake, and libtool

1998-07-16  Michael Pruett  <michael@68k.org>

        * Changes for the Audio File Library version 0.1.4.

        AES data functions are now implemented.  They're only effective
        whenusing the AIFF/AIFF-C formats.

        Miscellaneous data functions are now implemented for the
        AIFF/AIFF-C file formats.

        The Audio File Library now uses GNU autoconf.

        The Audio File Library now builds shared libraries.

        Some rudimentary documentation is now included.

1998-06-22  Michael Pruett  <michael@68k.org>

        * Changes for the Audio File Library version 0.1.3

        The Linux-specific test programs should work on all Linux
        platforms which support audio.  (I believe this includes just
        Linux/i386, Linux/PowerPC, and Linux/Alpha.  I may be wrong.)

        The function afReadFrames now returns the proper value.

        The afGetInstParams, afSetInstParams, afGetInstParamLong, and
        afSetInstParamLong calls are now implemented to the same extent
        that SGI's versions are.

        Instrument, marker, and loop data functions are now fully
        implemented.  I'll eventually get around to the miscellaneous data
        functions.

        The AUpvlist functions have been implemented and tested.  The
        afQuery calls are on my list of things to implement.

        A few minor bugs have been fixed.
