By default, Sound Juicer wants to only rip to either FLAC or Ogg formats, and if you live in the real world you’ll probably find MP3 is a more suitable format. Here’s the steps you need to complete to make SJ rip it up.

Make sure you have the multiverse repositories enabled, and:

sudo apt-get install lame gstreamer0.8-mad

Open up Sound Juicer. Choose Edit, Preferences. Edit Profiles. New. Setup as shown in the image below, with the GStreamer Pipeline:
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc

If you want variable bit rate turned off, and the bitrate to be 256, you can append:
vbr=0 bitrate=256

Close Sound Juicer.

Open Applications, System Tools, Configuration Editor. Choose apps, sound-juicer. Change paranioa to “0″ and it’ll reduce error checking, but in my case increased the ripping speed by about 4 times! Maximum time saving.

Close gconf.

Open Sound Juicer and set MP3 as you’re default ripping profile. Enjoy.
