2012-04-22 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/laurentperrinet/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.
