Many home study courses like language courses come with cassette tapes containing audible lesson material. Constantly having to wind and re-wind those tapes to find the right fragment can become very annoying and might even withhold you from completing the course.
Converting those cassette tapes to CD is the solution! On a CD player you can more easily jump to the fragment you need and also makes it easier to replay the same fragment over and over.
Record the tapes using the Sound Recorder and subsequently use the track-splitting options in the Audio Editor to create separate tracks of each lesson.
You might even skip the step of burning the lessons on CD, but rather play them back in the Audio Editor. That makes it even easier to skip to the right lesson and to re-wind the last lesson.
