EDIT: I, more or less, figure out where it began/ended, selected that, cut it, dropped it into a track below, muted it. Worked pretty well. Anything else, or a better way?
I sang an extra word at the beginning of a tag line. How can I figure out exactly where it begins/ends? I suppose I just have to guess where it is visually? Do I highlight the suspect area in the vocal track and then what? Reduce sound to zero somehow? I am so new, I don't know how to take sound down to zero.
