	QSound is most likely derived from phasing and EQ; it may also be
working with timing cues to provide an extended stereo image. My only QSound
recording (currently) is Sting's latest album on A&M records. (I'm blocking
on the name right now, sorry.) It claims that sounds will be heard from
outside the speakers from a centered listening position. Indeed, the sound
did, to my ears, appear to be more spatious than on some other recordings,
but I was paying attention. However, the sound over headphones was somewhat
disappointing... there seemed to be a lack of a strong phantom center at
times.

	Don't expect anything like surround sound from QSound. But it does
seem to do some interesting things with two speakers.

	On a related note, wasn't Roland recently working on an
ambience/localization processor which could localize a sound in three
dimensions using only two speakers? I'll try to find the review if anyone
asks, but I think that this processor required the listeners to be centered
(as does QSound) and didn't "work" for everybody (as QSound does not).

	Very interesting, though. Oh, yes. Sting's album is called
_The_Soul_Cages_. (Very musical, but somewhat depressing.)
