Folks,
I've been reading up on the various proposals for 3D sound from a set of
stereo speakers. The 3D Audio Alliance is working on such a system.
Astound Surround is getting ready to market, Edward Choueiri is working
on the same idea (see:

Rubbish. Unless energy is arriving from the general direction of the supposed

confusing cues that attempt to fool the brain, but sadly (for the 2-channel

"Once they are in there". Which is why you can make things
work with headphones plus head motion tracking.

I think one has to distinguish here various factors.
First of all, if one subtracts the effects of head movements
on perception and also assumes that the listener is
willing to keep their head absolutely still, then
there would seem to be no problem with producing any
sound one cared to at the en

Even SRS TruSuround seems to be a lot better than this supposed new and
"super" technology, but maybe I am wrong on this.
