Hi again, Sherry

>>>For the echo in Audacity, you might want to check the Preferences settings (under Edit, of all places), and fiddle with the "play while recording setting" to see how that affects any "echo" you hear.

Aha! That did the trick. I unchecked "Software Playthrough- Play new track while recording it". I left the 'Play other tracks while recording new one' checked. I had to fiddle a long time with various volumes, but the best I could get it is with playback set to 0.7 and record set to 0.1. Now the spectograms are NEARLY identical. The newly recorded track is exactly 0.35285 seconds behind the original track. I guess that explains the horrible echo when trying to record . I don't think it's a coincidence that the latency with my AC97 Audio is 35MS. hmmm! Anyway, I think there is a way to line up those two tracks, but it isn't a necessity because I don't need them to be together to record the new track by itself.

Thanks again!
Fred
