It’s really that easy! Just edit the config file and you’re good to go.

Jack transforms your audio-CDs to MP3 or Ogg Vorbis files. It uses several helper programs in order to achieve things like ripping, encoding and ID3-tagging. Ripping is either done via cdparanoia (in which case the ripping status is displayed by Jack as well) or cdda2wav. Jack works with several encoders, namely oggenc, lame, gogo, bladeenc, l3enc, mp3enc and xing. Any time during operation (and even when everything is finished and the original CD lost) you can let Jack look up the track names at freedb.org and rename the tracks accordingly. ID3-tagging of MP3s (or insertion of equivalent comment fields in Ogg Vorbis files) is performed as well.

If no freedb-lookup has been performed, Jack drops all files in a directory ~/jack/jack-xxxxxxxx, with xxxxxxxx representing the CD’s CDDB/freedb disc ID. This directory is renamed by Jack when the appropriate information is known.

Most options like ripper, encoder, preferred freedb-Server, directory and MP3-filename format, etc. can be user defined by changing the defaults in /etc/jackrc or by saving them to ~/.jack3rc.

**The default is set to Ogg so if you want MP3 be sure to edit the config file.
