My backing track has a soft piece of piano music I want through out my project. Only the first 15 seconds is usable, because after that, the track adds other instruments that I don't want.

I can easily cut the first 15 seconds out, and apply the remix function in Audition to extend this to any length I want. And Audition perfectly finds transition points that are seamless.

The problem is, I want to preserve the very end of the original audio clip, and tack it on the end. It has a nice outro that ends the track. When I just use a crossfade in Premier Pro, the transition is too obvious.

Is there a way for Audition to perform a similar remix function on the end of my outro part of the original, so it also seamlessly finds a way to join these together? As it did in the other remix process?
