Description Brion Vibber 2011-10-31 23:15:31 UTC 
For uploading higher-quality audio source material, it would be nice to support open lossless formats; Apple Lossless is now available as open-source so this should be feasible: <http://alac.macosforge.org/trac/wiki>

Transcoding to our standard output formats (eg .oga Vorbis) would be useful to keep playback support consistent.
Comment 1 Jan Gerber 2011-11-19 11:46:54 UTC 
ffmpeg supports decoding alac for some time, so TMH transcoding would work.

To support upload without Firefogg, some way to  detect if a selected .m4a file contains alac or aac would be needed. Could not find an existing implementation.
Comment 2 Marco 2012-12-05 17:05:17 UTC 
Not sure right now but I think we already have support for FLAC. Just because there is another OpenSource Codec for lossless audio storage it does not mean we have to implement it.

Duplicate? https://bugzilla.wikimedia.org/show_bug.cgi?id=49505
Comment 4 Andre Klapper 2013-07-01 09:30:34 UTC 
Kelson: How is ALAC related to FLAC? Also see comment 2.

I'm simply mixing different stuff. Sorry :(
