Does anyone know of a free (or cheap) program or Pro Tools plugin that will allow me to slow something down over time? By that I mean I don't want to slow down an entire region of audio to one speed, but rather have it slow down gradually. Can Pro Tool's included Time Shift plugin do this? I haven't had much luck using it without pitch shifting. I have a song in my current show that needs to start at one tempo and then towards the end it needs to retard to roughly 20 bpm slower.
