I'm looking for an efficient way to add space back into voice over edits. There are a ton of them and I had to do a lot of cuts. What I want is to take a clip of audio with nothing but silence but still room noise and mic noise and insert it between each edit so the cuts don't drop to total silence. I know I can do it manually but was hoping there is some kind of quick way to do it. I have plenty of "space recorded that I can use to fill it. Does this make sense to anyone out there. I would LOVE some help on this. THANKS. Sam
