Comes with Audacity software, which helps convert your casette tapes to mp3 files (or AIFF, or Ogg Vorbis, if you prefer). You can record a whole side of a tape in one go, and then easily chop it up in its separate tracks if you like. I am not a techie and found it all quite easy to work. Sometimes I had a strong buzz coming in over an otherwise clean tape; stop the machine, switch it all off and on again, and it is fine again. Not quite sure which caused this, not dirty heads (I cleaned these a few times with proper cleaning solution) not a bad lead connection. Anyway, I converted all my tapes to my satisfaction; just as I did earlier with all my records, using an ION record deck. A useful machine!
