Hello, I am wondering if there is a way to adjust the speed/pitch of my cassette deck using my computer? It was running too fast so I adjusted the speed control for the motor. Ithink it's very close now but maybe a bit too slow. I can plug the tape deck into my computer's audio inputs. I would like to know if the computer can tell me if the cassette deck is running at the correct speed.
