Function
It's not a plug-in, it's a function.
hold down ALT then stretch/squeeze the track with your mouse on the left or right side of the file (depending on how you need to manipulate the file).
by stretching i mean act as if you are going to loop a file, or edit the tale end of a guitar track that needed to stop at a certain time.
holding down ALT with change the normal function.
I had a client that came in just a little to late on a vocal part but caught up to the beat at the end of the phrase. He thought he would need to re-record that part.
I split that phrase from the track, kept the ending where it was, but then stretched the beginning to the left a little and lined it up with the kick.
You should have seen the look on his face! it was perfect, same pitch and everything.
I tried this in Pro-Tools, but i needed a certified letter from congress just to make it happen. Took less than a minute in Reaper.
