Email me when discounted: 
A52Codec is a CoreAudio component that can decode stereo and 5.1 surround sound from A52 and AC-3 audio. This type of audio is often found in DVD movies.

From the Developer:" I'm no longer maintaining this app as a separate download; Instead you need to download Perian to get the latest version."

What's New

Version 1.7.6:
  • Allow the setting of dynamic range. Can make soft sounds louder.
  • AC3 passthrough. This is a hidden pref since it requires special conditions. It is best set by the application after it has completed such setup.
  • Fixed bug with badly packetized data
  • Fixed a case where the audio was being clipped
  • Fixed an incorrect assumption about sample rates.
  • more...

Requirements

  • Mac OS X 10.4 or later
  • QuickTime 7.0.1 or later

Perian is now listed as discontinued in 2012, so is it known where users should go for an updated (i.e. newer than version 1.8.0) A52 Codec for OS X PPC and Intel?

I installed the XviD Codec Component 1.0 alpha, but no sound, and I still can't get audio after installing the A52. Any ideas?

Without this codec, AC3 audio isn't playable in apps that rely upon QT. (Of course, VLC doesn't have an issue but that's because VLC is self-contained and has all of the requisite components and codecs built-in.)

This codec plus Perian plus Flip4Mac's free component let virtually everything play in your QT apps.

Thank you!

Please, do what Apple did'nt,
Allowing play ac3 in mpg, vob, and TS multiplexed in QuickTime. And this codec will become a must have…

This is entirely Apple's fault, and only they can fix it. Demand it of them: http://bugreporter.apple.com

is why I ask you. Maybe you could do something ?
