Hmmm. So, I'm using the app in a way you didn't imagine? I can see that, now. That's too bad; I don't think there's an audio enhancement app available that can use AU plugins the way Audio Hijack can. I've looked at Hear and Boom2. Even if I am "abusing" (heh!) AH, I don't think my main point should go un-noted: give the user the option to keep all AH operations within one window. It seems like others agree that some sort of solution should be available. As a sometimes amature sound artist, I'd like multiple sources available to switch between and record as quickly and easily as possible. And, of course, I'd like to be able to route them through AU plugins. Thanks for your comments and attention.
