I'll quite often hear a shot from while turning my head, and that shot will be 'stuck' in the direction of origin in my headphones, what I mean by that is that if I hear a shot in my left ear, and I turn around, it will still be ringing in the left ear, making it much more difficult to pinpoint the source of the sound. It'd be nice to have the audio track the location like in real life.

What type of play are you looking at?

I feel the only way to accomplish what you want accomplished is to have them "standby" until the room/area is clear. Problem b eing then they know that they had to wait because the room was occupied.
