I just browsed David Griesinger's papers at his homepage (search with
google, say). There is a paper (AES '92?) which gives angles for
different microphone types for achieving uncorrelated recordings.
Is that something Ambisonics is about?

Anyway, Griesinger has a patent on some matrix, and his papers deals
with surround sounds. Something close anyway. :-)
