It's true you can use Music Match Jukebox as directed in the previous post
and I have done it. But...
I think you should look for Audio Cleaning lab from Magix. You can remove
the tape hiss and work with the audio file in ways MMJB doesn't allow.
I like MMJB enough to have paid to upgrade to Plus. I use ACL to split a
cassette or LP into tracks and remove the noise. Then I use MMJB (Plus) to
convert the wav files to mp3PRO. I've done hundreds, and some sound
exceptionally good. Some sound awful, but I sure didn't want to buy
replacement CDs for the best audio when I had so many cassettes and LPs
sitting in the attic.
The downside is typing in tags. IF the edit screen in MMJB didn't require a
mouse to go from side to side it would be way faster.
