I use Audacity regularly to do just what you need. You can clean up the recording to a degree before you finally export it as a .wav file for burning to a CD. By that, I mean that getting rid of rumble is fairly easy, but getting rid of tape hiss is a problem because you also get rid of some of the high frequency notes that give the recording its "life".
