I have a Marantaz dual cassette deck, that I run through my interface, and use with my pc to convert cassettes to digital format. I use audacity recording software, and for the first time, one of the cassette decks from the Marantaz did not record as normal. The audacity I had recording in stereo showed one normal healthy looking wave, and one thin looking wave under neath. The end result was the sound recording was lower, so I put the tape into the other cassette deck, and I am trying to figure out if the cassette deck is recording into audacity normal now. After I started recording in the second deck the audaicty wave recorded in stereo looks noticeably smaller than the wave above, but is shaped the same. Is this normal? The cassette recording is not of the best quality. Most of the sample pics of audacity waves, I have found online show the two audacity wave forms recorded in stereo looking almost identical.
