Welcome to the A52Codec development page.  From here, one can [http://trac.cod3r.com/a52codec/browser/ browse the source], [http://trac.cod3r.com/a52codec/search search existing tickets] or [http://trac.cod3r.com/a52codec/newticket file tickets].

== Download ==
A52Codec is now included in [http://perian.org Perian].  I'm no longer maintaining a separate download.

== About this Codec ==
This component was originally written by Shepmaster.  His page on the codec is [http://shep.thefridgeowl.com/a52codec.php here].  This version does not work on Intel and often doesn't work on PPC, so I took this program in May of 2006 and rewrote it to fix these shortcomings.

=== Major Features ===
 * Multi-channel decoding of AC3 audio (can do full 5.1 decoding).
 * Implemented as a core-audio component so it is available to both Quicktime and Core Audio components.
 * Includes an AC3 importer so QuickTime can read .ac3 files directly.
 * Includes a preferences file to enable or disable dobly surround encoding as well as dynamic range compression.

Version history is available at ChangeLog

== Using this Codec ==
Installing this component is rather simple.
 * If you wish to to be available to all users on the system, simply copy {{{A52Codec.component}}} to {{{/Library/Audio/Plug-Ins/Components}}} and {{{AC3MovieImport.component}}} to {{{/Library/QuickTime}}}.
 * To install it for a single user, copy {{{A52Codec.component}}} to {{{Library/Audio/Plug-Ins/Components}}} and {{{AC3MovieImport.component}}} to {{{/Library/QuickTime}}} inside the user's home directory.
Quit any open Quicktime applications, (including !FrontRow) you wish to use this component and relaunch them.
 * Lastly, be sure to remove all instances of AC3Codec.  It does not work properly and can cause severe problems on Intel machines.
