Free ac3 software for mac

AC3 Codec is a QuickTime component which allows the playback of AC3 audio inAVI files. The component uses the liba52 library for the AC3decompressing.

First you need DivX 5.1 which correctly load the AVI file into QuickTime. Once you have DivX 5.1 installed, if you are on MacOS X, drop "AC3 Codec.component" into /Library/QuickTime, or if you are on MacOS 8.x/9.x, drop "AC3 Codec" into your Extensions folder and restart.

Thats it ! Now open an AVI file that has AC3 audio, and play !

ENJOY !

The GeeXboX is no more than an awesome standalone media player. Why such a name ? Well, its main purpose is to play DivX movies and, as everybody usually call this kind of projects DivX boxes, well just prepended a "GeeX", cause thats for the geeks you all are ;-)
So, GeeXboX is a full operating system, running under Linux and based on the excellent MPlayer. No need for a hard drive, you just have to put the GeeXboX bootable CD into the CD-Drive of any Pentium-class computer to boot it. Moreover, GeeXboX is free software, created as open-source software. This means that everyone can modify it and build his own release of the GeeXboX.
You may wonder why you should have to boot another operating system to play your media files, but just think about the Mini-ITX platforms like VIA Epia/Eden or Shuttle barebones. Its now affordable to bring DivX to your home cinema, plugging this kind of computer directly to your TV !!
At the time of the first development releases (Dec. 2002), it was only capable of playing DivX movies, but now, nearly every kind of media file can be played with GeeXboX, with the OS supporting :
- MPEG 1/2 movies (MPG files, VCDs, DVDs ...)
- MPEG 4 movies (DivX, XviD ...)
- RealMedia and Windows Media movies.
- OggMedia streams
- Matroska streams
- Audio streams like : MP3, Ogg/Vorbis, WAV (AudioCD), AC3 ...
GeeXboX is an operating system but you still need something to boot on ;-) Youre lucky, GeeXboX is based on MPlayer, which can be considered as one of the less cpu-dependent movie players, thanks to the use of FFMpeg for decoding movies.

djoPlayer is a very simple, yet highly customizable, GUI for MPlayer. It allows you to play DivX 3, 4, 5, Xvid, Vob, mpeg-1, mpeg-2, mpeg-4, asf, wmv, ac3, mov... files with the subtitles if any!
It was the first GUI that allowed you to enable the Post Processing for MPlayer (it blurs the usual squares that you see in DivX movies).The website is in French, but the application (made with AppleScript Studio) is in English too.
Enhancements:
- Small bugfixes.

bd4go is a Cocoa tool to convert ac3 format audio files to aiff or wav audio files.
Enhancements:
- added the nice icon by Randy Knoble
- close button of window quits the app now.
- added high quality (slow) sample rate conversion, based on ssrc-1.29 by Naoki Shibata. Which is currently working only with .wav output and a fixed sample rate of 44.1 kHz. It uses another thread to boost performance on dual processor machines but is still too slow.

MPlayerOSX is binary distribution of MPlayer (The Movie Player for Linux) and comes with native GUI in Mac OS X. After installation you can simply (by Drag&Drop) play almost all 3ivx, DivX 3,4,5 and other codecs files in the window or fullscreen mode.
Rendering of very nice antialiased text-based subtitles is also supported.
Multimedia player with playlist, supporting playback of all widely used media types (MPEG 1-4, DivX, AVI, ASF, Ogg Vorbis, RealMedia, QuickTime Movie, MPEG layer 1-3, AC3, WindowsMediaAudio etc.) and movie subtitles of various formats (MicroDVD Player, Subrip, etc.).
It is based on MPlayer - movie player for linux.
MPlayer has very good postprocessing. On every image in the movie is applied a filter to reduce square areas, which comes from codecs compression algorithm.
Enhancements:
- recompiled for macosx 10.4.
- its ONLY FOR 10.4. or better (if you have 10.3.xx use older version)
- there is new -vo based on cocoa and coreimage
- NO GUI CHANGES
- there are problems with some audio files.

MoKgVm2DVD is a useful tool that provides the tools needed to prepare .ogm and .mkv files for use in DivX enabled DVD players.
These players typically require videos to be in AVI container files (i.e., have .avi extensions) using any of the following codecs:
Video: mpeg4 (e.g., Divx or Xvid) but not h.264
Audio: mp3 or ac3 but not ogg/vorbis or aac
Most players will also support separate subtitle files. Typically the subtitle file must have the same name as the .avi file.
MoKgVm2DVD will let you select the tracks from the .mkv or .ogm file and either copy the tracks to the new .avi file or, if needed, re-encode the track(s) using the XviD codec. You can also extract any of the tracks into separate files.
The table below shows the current abilities and limitations of MoKgVm2DVD based on limited testing. Please let me know if you have different results.
Enhancements:
- Fixed a bug that caused MoKgVm2DVD to prematurely stop the conversion process
