While editing some vocals the other day, I accidentally hit a key in Vegas and the scrub head started going backwards, playing my audio in reverse. I wasn't trying to do this at the time and got it playing normal again. Today I was thinking that this could be useful when trying to find a point where the vocalist takes a breath. Rather than guess, split the clip and play from a few seconds earlier to hear if it is gone, then repeat the process, you could just set the play head past the breath, play it backwards and find the exact point that they start their breath.
Does anyone know the key you hit to play the scrub head backwards in Sony Vegas?
(This is not flipping the clip to play in reverse using "Right-click/Reverse", I don't need that, I just need the play head to play in reverse temporarily, like scrubbing it backwards)
