-a52dec-0.7.3 Wed Feb 20 23:38:22 PST 2002
--rewrite of the imdct code, making a52dec 40% to 80% faster than version 0.7.2
--fixed one memory corruption problem in parse.c
--small liba52 portability fixes
--byte order and CRLF bugfixes in wav file output
--aif file output
--IRIX al sound output (untested, tell us if it works)
-
-a52dec-0.7.2 Sun Dec 16 14:39:56 PST 2001
--demuxer improvements, with support for TS streams.
--smaller demux buffer, making it easier to use a52dec as a pipe
--wav output
--avoid -fPIC when possible (-prefer-non-pic)
--support for vc++ and TenDRA
--portability fixes
-
-a52dec-0.7.1b Fri Aug 31 02:37:23 PDT 2001
--removed an #include <stdint.h> that was only breaking libc5 builds
-
-a52dec-0.7.1 Thu Aug 30 02:13:23 PDT 2001
--gcc 3.0 fixes
--mlib fixes (now passes the test suite)
--in a52dec.c, made sample_data and flags static
--removed a few statics in liba52/parse.c (still not reentrant, but closer)
-
-a52dec-0.7.0 Thu Aug 23 23:18:00 PDT 2001
--Downmix to arbitrary speaker configurations
--Dynamic range compression

- 3x for 5.1 streams with 2.0 output.
--New library interface
--Rematrixing bugfix

-ac3dec-0.6.1 Mon Mar 27 20:27:06 EST 2000
--Fix another 2.0 problem (rematrix was wrong).
--Fix the never resync on a bad crc bug.
-
-ac3dec-0.6.0 Sat Mar 18 19:43:25 EST 2000
--New library interface
--Fix bug wrt coupling channels that was causing sound quality problems.
--Fix 2.0 mode problems (aka the I forgot to implement the phase flags bug).
--All around speed improvements (almost twice as fast)
--Improved robustness when fed bad data. The entire frame is checksummed before playback.

-ac3dec-0.5.6 Tue Nov 16 00:37:34 EST 1999
--Irix support
--Alpha fixes
--Minor performance enhancements to downmix and imdct
--OpenBSD fixes
--extract_ac3 can now read from stdin
--Change output_linux to block on write instead of using the
- ring buffer. Let me know if this causes/fixes any problems
-
-ac3dec-0.5.5 Wed Aug 25 15:36:44 EDT 1999
--Fixed a cut and paste bug (argh!) in parse.c which potentially
- screwed up delta bit allocation info.
--Martin Mueller <mamueller@topmail.de> informed me that I was missing
- some corrections from the AC-3 errata document. It turns out that
- I used an earlier version of the errata when I initially wrote ac3dec.
- Fortunately the errata fix the outstanding bugs that I was pulling
- my hair out on for a long time. Woohoo! Thanks Martin. Kudos to Dolby
- Labs for keeping their documentation up to date as well.
--stereo downmixing (downmix.c) is now in. Matrix encoded surround
- (Dolby Prologic Surround) should work too.
--clipping due to high level signals has been fixed. We normalize a
- block of samples by its maximum absolute value if the max exceeds
- the %100 digital level. This shouldn't be a problem, but for some
- reason some channels have a dynamic range that exceeds [-1.0,1.0].
- I blame the encoder :)
--Multiple track support in extract_ac3. Simply just give it the track
- number you want [1,8] after the filename.
-
-ac3dec-0.5.4 Thu Jul 29 16:55:10 PDT 1999
--Fixed a stupid bug with the coupling channel that was causing
- high frequencies to be attenuated.
--Re-wrote the extract_ac3 tool.
--Added to a tool to verify the checksums on a given AC3 stream.

--Minor performance enhancements

-ac3dec-0.5.2 Sun Jul 4 12:00:25 PDT 1999
--output_linux.c patch provided by Michael Holzt <kju@flummi.de>

-ac3dec-0.5.1 Wed Jun 30 17:48:52 PDT 1999
