I have a scratch track that needs to be replaced and I want to keep my effects and keyframes.
I can do this in Soundtrack Pro, but cannot find it here.
Please don't tell me this is a CC feature!
There's isn't yet a quick method of relinking a clip to a new audio file. Fastest workaround that I can recommend right now is to close the session, then rename or delete the scratch track. Next time you open the session, Audition will ask you to select a file to replace the missing one. Choose your final audio and save the session.
