I have been using Cool Edit Pro to copy audio casettes to my hard drive and burn them onto cd for a few months now. My latest venture, the unabriged Harry Potter books suddenly disappeared. 35 hours of tape playing vanished and now, Cool Edit won't record anymore. The casette player is patched into the computer and I can hear the tapes playing fine but, when I try to record, nothing is copied. Cool Edit acts like it is recording although, I don't have the visual waves as the tape progresses like I used to. It scrolls along in time, it just doesn't seem to be recording anything. When I try to play back, I get nothing, just dead air. Have I inadvertently done something stupid? Is there some setting somewhere that I changed without meaning to? Anyone have any helpful suggestions?
