- 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.
