Converting FLAC to AAC (or MP3 to OGG etc...)

• the solution is http://audiotools.sourceforge.net/

• installation on MacOsX Lion (with homebrew) :

  brew install libcdio
  brew install lame two-lame mpg123 mp3gain
  brew install libogg libvorbis     vorbis-tools  vorbisgain
  brew install faac faad2
  git clone git://github.com/meduz/python-audio-tools.git  audio-tools
  cd audio-tools
  make 
  make install

• using it:

  track2track  -t aiff *.flac #lossless
  track2track  -q 0 -t m4a *.ogg #lossy

• and on a whole folder, placing the files in the same directory:

  find a_folder/with/lots_of_flac -name *flac -exec sh -c 'echo "Processing $0"; track2track -t aiff  "$0" -o "${0%.flac}.aiff"' {} \;
  find a_folder/with/lots_of_ogg -name *ogg -exec sh -c 'echo "Processing $0"; track2track -t m4a  "$0" -o "${0%.flac}.m4a"' {} \;

• tried as a formula in homebrew: https://github.com/mxcl/homebrew but closed it.
