It's only a tiny point, but Sampo, you said "... because our vertical resolution is so bad..." Strictly, our perception in the vertical plane isn't the same as in "elevation", except for the special case where the head is kept still, not tilted. 'In the wild', we do move and tilt our head, especially when auditorily interrogating the environment, resulting in acuity for vertical information that is more similar to that for horizontal than the literature might suggest. I know it's a convenient shorthand to equate azimuth with horizontal and elevation with vertical, but it's handy to remember they aren't identical ;) Cheers ppl

Under heavy assumptions you can, because our vertical resolution is so bad, staged sound is so stereotypical (partly because of past limitations in transmission technology), and because the variability in individual HRTF's means some contingent of the whole populus will always like even bad degraded against the mean reproductions. That's how 2-to-7.1 upconversion folks make their living. Still, it requires prodigious amounts of processing power and deep psychoacoustics to do even that, and the result only works in a very limited setting. It has nothing to do with ambisonic, or even its highly processed forms like various infinite order dynamic decoding matrices. Such things assume *much* less about the sources than these kinds of schemes do, both physically and psychoacoustically. So no, "this thing is not ambisonic". Maybe we should have a list of things that aren't, BTW, given that people keep on reinventing the wheel? Maybe as part of the motherlode? :) -- Sampo Syreeni, aka decoy - de...@iki.fi, http://decoy.iki.fi/front +358-50-5756111, 025E D175 ABE5 027C 9494 EEB0 E090 8BA9 0509 85C2 _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound _____________________________________________________________________ The University of Derby has a published policy regarding email and reserves the right to monitor email traffic.
