How to incrementally slow down audio (or video)
I'm looking for a tool where I can smoothly slow down an audio clip from regular speed to a much slower speed, over the course of several seconds, as if a turntable motor lost its power and slowed to a stop. I'm still using Final Cut 7 for video and I know how to change the speed (command-J) but that'll do it for the entire clip, not incrementally slow it down. Any ideas/suggestions? Thanks.
Final Cut Pro 7, OS X Mountain Lion (10.8.5)
