[NewMusic] Core Sound ambisonic mics

[David Slusser]

A colleague told me he had demoed the Core system, and
was not impressed with the capsules back when he did it.
He recommends the soundfield system, which he said
sounded pretty darned good on its own, outside a surround
situation.  He also said using the matrix box, you can
encode all the channels to a stereo pair, and then at a
later date decode for multi channel.
