DESCRIPTION
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.

Note: I'm no longer maintaining a separate download, but instead you need to get 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.
  • Fixed an error with an incomplete sample at the end of a file
  • Added the ability to output Pro Logic II
REQUIREMENTS
Mac OS X 10.4 or later, QuickTime 7.0.1 or later.

RUMPLESTILTSKIN  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!

GSNXN  Does A52Codec 1.7.6 conflict with Perian 1.0 (which, I believe, includes A52Codec 1.7.2)?

NGLESTER  Hi all, i am having problem with my AC3 videos on the Quicktime player. After i installed the "A52Codec 1.7.2", all of my AC3 videos get a white "blinking" bar on the right handside of the QT player while playing the video.

I tried the same video same add-on on the G5 ppc, but everything runs smooth and fine. Any of you guys know i can get rid of this problem?

Please help, thanks a lot

NGLESTER  No need for further help, i got it solved. That blinking line was cause by Divx 6.6 + A52Codec. Apparently these 2 won't go well together. I had to trashed the whole divX 6.

Installed the Perian 0.5, works perfectly fine now.

FOLLEREC  This, together with Perian, NicePlayer, and MPlayer OSX, completes my video playing requirements for probably any type of video (or at least those that I do play).
