Hello fellow Audacity users: I have an audio track and a dry voice track and I'd like to overlap the two, so that the dry voice track will begin playing at a certain point within the already existing audio file. Someone on the list said that the easiest way to do this, was to select the portion of the existing audio where you want the other track to begin, by playing the file and then pressing shift A. But it seems like there's one other step prior to that, which I can't quite remember what it is. Could someone explain again how to do this? Thanks. Mike Rochester, NY.
