I have a collection of over 200 music cassette tapes, and I have been going through the process of copying the contents of these tapes into digital format and storing them on my computer. This process is fairly straightforward, but it does take time. At the high level, what you need to do is to use a software program to record the music on your computer by playing the cassette tape in a tape player and connecting the tape player to your computer. Then, you can store the music on your computer in your favorite format.
1. A cassette tape player.
2. A 3.5 mm male-to-male audio connector such as this one from Amazon.
3. An audio editing program called Audacity. You can download this program from the website.
1. Plug one end of the audio connector into the tape player, and the other end into your computer.
