Ripping a CD to mp3 isn't that easy for a debian newbie. This operation require a package that is not available from the official package repositories.
Mp3 record profile
Open gnome's audio preference panel. You can access it from Sound Juicer, "Edit", "Preferences", then "Change profile..." or from a terminal with
Check for a profile named "CD quality, MP3". If there is no such profile you can create it. The gstreamer pipeline must look like:
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr-quality=6 ! id3v2mux
You can change the vbr-quality value (between 0 and 10, the lower the better). If you want to use a 192Kb/s constant bitrate you can use
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 bitrate=192 ! id3v2mux
Don't forget to activate this profile.
You now have an mp3 profile but it's still not available from the output format list shown by Sound Juicer. We must install the mp3 encoder: gstreamer-lame.
Lame encoder installation
Due to non-respect of Debian policy, the gstreamer-lame package can't be found in official package repositories. But it can be found in several alternative repositories. I updated my /etc/apt/sources.list file and installed this package from debian-multimedia.org.
~$ cat >> /etc/apt/sources.list << EOF
deb http://www.debian-multimedia.org testing main
~$ apt-get update
~$ apt-get install gstreamer0.10-lame
You can now restart Sound Juice dans open the preference dialog. The ouput format list should now contain the "CD quality, MP3" .
