Q. How can I play and record cassette tapes on my computer?

Hello:

Most computers have a line-in for Audio.  You would simply need to use a cassette player with a line-out, and plug it into the line-in on your computer.  Once connected to your computer, use Audio/Recording program to capture the sound.
