Most cassettes are simply stereo so that's all of 2 tracks. Left and right. Let's say you want to put each into it's own MP3.

I have been using ExpStudio but there are several issues with the program and my computer. Is there another program I can use to separate the tracks on a cassette that I downloaded to my computer? Thank you for suggestions.
