Very funny, Twisted.

Seriously, I agree that you can absolutely hear small differences as you move your head from side to side, but in real world conditions, one-foot increments are just fine (probably even too small to be realistic, actually.)

Understand that films are often mixed in large soundstages/theaters where the engineers aren't sitting at one-foot tolerances. In fact, they ordinarily aren't using delays at all. The delay is a home theater device designed to help recreate the large theater experience and the speaker distances involved in those settings.

In short, since I think our ultimate goal is to reproduce film sound as accurately as possible (or multichannel audio) I think there is a lot more "slop" in the process than delay distances of less than one foot. MUCH more slop.

In general, I think home theater listeners using the foot settings in their pre/pros tend to OVERuse the delay. I've always found that reducing the amount of delay a bit from the pre/pro "sanctioned" settings tends to lock in a more solid surround image and give the sound more punch and intensity. So I usually start with the pre/pro footage settings and then reduce the amount of rear delay until I get the sound I like from my listening position. (Other people in the room are on their own. )
