This hedgehog layout really fits to the microphone openings of the Ozo
camera...
btw, since you're quoting this very interesting article, it has been
partly superseded by recent research of lee at al. at huddersfield
(see latest JAES), who found that there is _no_ vertical precendence
effect and that interchannel time differences in vertically spaced
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.
There is actually even not an ILD cue. You will have level and spectrum
cues caused by the pinnae. Maybe some other effects. (See also Bo-Erik's
posting...)
Best,
Stefan
No vertical precedence: Could be very much related to this simple
observation. (I guess IC cues will also not matter.)
Do I miss s.th.?
helmut is aware of this and has presented a much more compact
8-channel mic array at ICSA 2015 in graz, where the top and bottom
mics are practically coincident.
Will look into this.
Tschüss,
Stefan
