Yeah on Cool Edit, to put in a bit of silence just go to "Generate", and "silence". Make sure your marker on the audio is at the beginning, you don't want to put the silence in the middle of the tune. ;) You can also do this on Nero, I believe it's once you drag a track over. Highlight it and there should be a option to insert silence. Also your going to want to record each song/track seperately. Don't record the whole CD or whatever as one audio file. Record each track and save it, then place them together in Nero, so you have a track list. I know you probably know this but from your post I wasn't sure. Have fun!
