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.
Fixed an error with an incomplete sample at the end of a file
Added the ability to output Pro Logic II

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!

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

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).

CAN NOT GET AUDIO FROM AVI FILES IN QUICKTIME?
GO TO http://perian.org/ DOWNLOAD AND YOU WILL.
IT WORKS.
WHY NOBODY CAN JUST COME OUT AND SAY THIS IS BEYOND ME.
I HOPE THIS MAKES YOU AS HAPPY AS IT DOES ME.

Finally AC3 encoded Movie file can be played smoothly in Quicktime Universal Binary! A big THANKS to 'Graham Booker', the developer who apparently fulfilled my expectation unexpectably well :P

Excellent. The intel mac community has been in dire need of an AC3 codec (there have been a couple of random unsupported builds floating around, but they are pretty flaky).

Excellent work! I just tried it on my MacBook and it works like a charm. Finally, a working AC3 decoder for Intel-based Macs! Congratulations.

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?

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

nglester had trouble on 08 Dec 2006

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 commented on 08 Dec 2006

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.

Mac NOOB here. After downloading and double clicking, the A52Codec just opens it in Excel. What program do I need to decode/install this codec? Or what am I simply doing wrong?

Rename A52Codec to A52Codec.dmg and double-click. It should mount on the desktop.

ShannonRawls had trouble on 22 Aug 2006

I agree, with this plugin, Quicktime still will not play AC3 encoded VOB or MPG files. I authored a DVD on a PC using Sony Architect with AC3 audio. I ripped it with MacTheRipper, and it will not play audio with Quicktime. I am looking for a solution.

Giving you the same response:

One user reported ( http://trac.cod3r.com/a52codec/ticket/6 ) that this worked, but I have been unable to reproduce his results. Two things lead me to believe that this is the fault of the vob file importer and not the codec.
1) If you open a .mov or a .avi file without the component, then QuickTime Player shows a dialog box telling you that you are missing components. No such dialog with .vob files
2) Even if QuickTime Player is unable to find a codec, it still will shows the audio bars on the right if an audio track is present. No such bars.
I believe that Apple's vob file importer is not doing its job correctly. If this is the case, then the fault lies with them, not with the codec.

P.S. You would receive faster response if you post to the ticket tracking system than if you post here.

Does not work for me. After installation as instructed, Quicktime still cannot play the sound when viewing a .VOB file.

I'm not able to get this working. I tried filing a ticket but it apparently disappeared. iTunes and Quicktime will not play the .ac3 from:
