I guess I should have mentioned my setup. All I am trying to do at the moment is transfer the sound from a cassette tape to my PC and then from my PC to a CD.
I am using the "line out" from my cassette player to the "line in" of my PC soundcard (Sound Blaster) - and I am using n-tracks to make the recording. There is no microphone being used at all, but the recording sounds sort of "hollow".
Any ideas?
