Install latest Ecasound snapshot from:

Then install FAAD2 from:

Optionally install mpg123, FLAC and vorbis-tools (probably you already 
have these).

And then you can just do:

sh> ecaconvert .wav *.m4a 
sh> ecaconvert .mp3 *.m4a 
sh> ecaconvert .ogg *.m4a 
sh> ecaconvert .mp3 *.m4a 

... and it'll convert all the m4a files. If you want to change the
encoding parameters, edit your ~/.ecasound/ecasoundrc (see ecasoundrc(5)
man page for more info).

 Audio software for Linux!
