Re: Now, to miniaturize...

It would appear to be predicated upon extraction of directional cues
from arrival times at the large array of mics. What the demo skates
over is that the mic array is relatively close to the court, there are
no other conversations going on in the immediate vicinity of the
person speaking in each of the short instances shown, and in the much
more reverberant audience space, all directional information will be
highly diffuse rather than direct, thus making accurate directional
cues pretty speculative. I wouldn't be too concerned at the moment
about the privacy of my conversations while attending basketball
games. Then again, maybe discussing illegal activities, proprietary
business plans, or illicit affairs in a crowd isn't too smart, if one
really wants to preserve ones privacy.
