I'm working on a scene where the referee of a basketball game comes back in the locker room after the game has ended, and he's supposed to be hearing crowd boo's in his head, because he made a terrible call during the game that's eating him up. The problem is when I throw a hpf and reverb on it, it just sounds like it's coming from the gymnasium. I've tried putting a reversed version of the boo's under the hpf one and it sounds a little too eerie for the scene.
Any suggestions would be much appreciated. Thanks all!
