View Full Version : AC3 to Applelossless

I'm looking for a way to transcode an AC3 Audio track from a MKV file to Applelossless.

I have already emailed the maker of MKVtools about the idea of adding the feature.

Until than, I already can transcode FLAC to Applelossless with the application XLD. So if someone can point me in the right direction of transcoding AC3 to FLAC it would be a great help. Than I could simply go AC3 to FLAC to ALAC (Applelossless)

I'm simply trying to do a 100% lossless transcode of a H.264/AC3 .MKV file to H.264/ALAC .mp4 since iOS and Quicktime X don't play too nicely with AC3.

Thanks!

Have you tried ffmegx? That should do the trick.

Ok I got FFmpegX 0.0.9y up and running on 10.6

Any further instructions you can send my way? no FLAC or ALAC options are jumping out at me in the application.

I'd use Audio Hijack Pro to do it.

I use eac3to (http://forum.doom9.org/showthread.php?t=125966) through VMware (link is currently unavailable but should be back soon). It's the most reliable way that I've found and it handles pretty much everything I throw at it.

Are you saying this from experience or from specs?

Looks like ALAC (http://www.qweas.com/reviews/comparison_of_container_formats.htm) is supported under .mp4/m4v to me.
