I'm using Reaper and I know when I do a project, I can clean up unused audio within Reaper.
I also record things on the fly with TwistedWave editor, and Ableton.
I believe Ableton has a setting to delete unused audio on quitting the particular session you're working on?
I was just wondering if I was missing a simple effective way to clean up anything that I had missed, as I do inevitably have a scattering of files from different recordings, and demos
