Для конвертации в Ubuntu нам потребуетются библиотеки:
mac - конвертер с/в ape-формат (Monkey Audio)
  #: wget http://members.iinet.net.au/~aidanjm/mac-3.99-u4_b3-1_i386.deb
#: dpkg -i mac-3.99-u4_b3-1_i386.deb
lame - декодер mp3
 $: sudo apt-get install lame

mp3splt - обрезка mp3/ogg файлов
 $: sudo apt-get install mp3splt

oggenc - декодер ogg
 $: sudo apt-get install vorbis-tools

#This script is intended to convert ape or flac + cue files to
#ogg vorbis or mp3 files, setting the tags to the correct value,
#obtained from the cue file.
#REQUIREMENTS:

# -lame installed if you want to encode into mp3
# -mac to decode ape files (Monkey's Audio)
# -flac to decode flac files.
