Cassates to CDs

I was wondoring is there any software out there that can take my cassate and turn them into .wav files on my computer. using the line in jack and such. I know I can sort of do that with musicmatch but I don't want to stay buy the computer hitting record, stop, and such. also is there any software that takes the fuss and buzz noies out the track once its on the computer?

Please help

EDIT: This is for cassates I already own. and for any recrodrings onto cassates I have done.

The SB Audigy comes with software that takes out hisses, pops, and other background noises. I used to use windows sound recorder to record *.wav files from the line in jack.
