I use Accoustica. For the $25 I spent it does alot more than just record - it allows sectioning, overdubbing, volume and pitch adjustment. It' sgreat for making samples to loop over just about anything. I shows recordings in a visual -liniar timeline sort of format so I can "see" the soundtrack.
but as I'm writing I'm realizing that you said "rip" audio - which means you may wish to quickly capture the sound file from something. This records in realtime, from input, CD, wave...
Might be helpful.
