I hated putting additional wear and tear on my precious old records, knowing that each time I used them to make a new tape I wore them out just a little more. Patching together troupe shows from a repertoire of songs that came from many different records and tapes was a tedious process. A sound card. Most new computers come with one of these. Software to extract music from your stereo system through the sound card.
Most sound cards come with such software.
Software to write music to your CD drive. Most CD recorders come with this. Software to edit music or other recorded sounds. There are a variety of CD writers in the market today. Some come bundled with software for creating music CD's, some don't.
