I'm interested in converting mostly cassette tapes to MP3 files for personal use. I have a late '06 Macbook (Tiger). I have a cassette deck and a cable that can physically plug into the audio out of the cassette deck and audio in of my MB. So I'm thinking I could use Audacity or Garageband to record it on the MB (haven't attempted it yet). BUT, I'm wondering what is the easiest way to separate it out into individual files for each song. Is there any way to record the whole tape and then mark each end/start of songs and the software will divide it out into files? Or do I have to manually record each song separately?? I'm not interested in investing in a USB device... Any suggestions?
