We record our practices using a 4-track but we only use two tracks. I want to put the practices on my computer so I can burn a CD of the good takes. It'll be easier to sort through the stuff and organize it in a practical manner. However, when I plug my Walkman into the soundcard input, the motor overpowers the practice. Is there a program that can clean that stuff up? Is there a better way of transfering the sound?
