btw, since you're quoting this very interesting article, it has been

loudspeakers do not contribute to localisation in any way.
? This is supposed to be new? Methinks there can be only ILD and
spectrum cues to enable height perception (but no ITD cues), because the
ears are positioned in the same plane.
No vertical precedence: Could be very much related to this simple
observation. (I guess IC cues will also not matter.)
well, obvious in theory, but nobody in the 3d audio world seemed to be
aware of it, and now lee has done the deed and pulled the rug from
under all those vertically spaced arrays...
the "new" part is that somebody actually got around to disprove it, in
a rigorous listening test.
VBAP still seems to work, at least at the front - and to "some degree"
elsewhere.
This is not necessarily a contradiction. If there is no < interaural

Do I miss s.th.?
no. but there is great value in moving something from the "everybody
knows that..." into the "rigorous listening tests have unambiguously
proven that..." realm.
VBAP localization tests have been done a plenty of times.
Best,
Stefan
