If that is true, then I guess the link I posted regarding
CNMAT/MeyerSound "eigenspeaker" is bunk?
I'm talking about a different configuration of ambisonics than the
traditional speakers around the listener and the associated sweet
spot. IMHO that's a somewhat difficult configuration, especially for
mobile apps, so I was just wondering whether the effect be gained with
only four speakers in a "polar" configuration.
And if not four, six, eight, or how many? Can they be arranged in a
"circle" around the perimeter or is 360 degree configuration of
drivers required?
