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.

	* 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.

	Davy Durham for noticing and fixing this problem.

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

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
	integer data in memory.

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.

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.)

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>

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.

	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:

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,

	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.

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

	* libaudiofile/audiofile.h:
	Corrected comma-in-final-element 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.
