It works, but sometimes I need to listen to the directions given to the speaker in between, but I could just isolate a region where I know there are many takes. It worked pretty good, it looked like this (sorry for the huge size)
But then I remembered when I tried this before, the regions would have this white line in them, what's that about? There's no overlapping or anything, and it stays in the same place what ever I do with the region. Not a game breaker exactly, but what is it?
