The short answer<\/h2>\n

If you want to converte audio between Free Lossless Audio Codec<\/a> and Apple Lossless Audio Codec<\/a> it’s straightforward as<\/p>\n

avconv -i audio.flac -acodec alac audio.m4a\r\navconv -i audio.m4a -acodec flac audio.flac<\/pre>\n
Where did this come from<\/h2>\n
This is the application from\u00a0Libav<\/a>\u00a0which is\u00a0a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec – the leading audio\/video codec library.<\/p>\n
So, you are in good hands!<\/p>\n
How to install avconv<\/code> in Ubuntu 12.04 LTS<\/h2>\n
You already know how to do it right ? Just use apt-get install avconv<\/code><\/p>\n
$ sudo apt-get install avconv\r\n[sudo] password for biafra:\r\nReading package lists... Done\r\nBuilding dependency tree\r\nReading state information... Done\r\nE: Unable to locate package avconv\r\n$<\/pre>\n
What ? This can’t be true!
\nBut it is because avconv<\/code> is just the new name of… ffmpeg<\/code>.<\/p>\n
At this time you still have to install it using the ffmpeg<\/code> name<\/p>\n
$ sudo apt-get install ffmpeg\r\n\r\n$ ffmpeg\r\nffmpeg version 0.8.1-4:0.8.1-0ubuntu1, Copyright (c) 2000-2011 the Libav developers\r\nbuilt on Mar 22 2012 05:09:06 with gcc 4.6.3\r\nThis program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes).<\/span>\r\nHyper fast Audio and Video encoder\r\nusage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...\r\n\r\nUse -h to get full help or, even better, run 'man ffmpeg'\r\n\r\nThe warning is just to tell you to start to use avconv<\/pre>\n
$ avconv\r\navconv version 0.8.1-4:0.8.1-0ubuntu1, Copyright (c) 2000-2011 the Libav developers\r\n  built on Mar 22 2012 05:09:06 with gcc 4.6.3\r\nHyper fast Audio and Video encoder\r\nusage: avconv [options] [[infile options] -i infile]... {[outfile options] outfile}...\r\n\r\nUse -h to get full help or, even better, run 'man avconv'<\/pre>\n
Update:<\/b> In Ubuntu 14.04 LTS just sudo apt-get install libav-tools<\/code><\/p>\n
Conclusion<\/h2>\n
The simplicity of avconv<\/code> is a must. Just use it to convert FLAC, ALAC and other codecs. Just a warning: mp3 is not supported. Check the available codecs with avconv -codecs<\/code>.<\/p>\n
