Hi,
Have you looked at any of Angelo Farina's recent work, which
essentially involves beamforming from an Eigenmike but without going
through the intervening step of spherical harmonics, which has some
advantages if you are looking at separating sound sources. A lot of
Angelo's work in the last

Without more details, it hard to speculate about problems, but I'll note

It might be stating the obvious here but how would you get ANY directional
information out of four OMNI mics close together? :-)
Surely to get a fig-8 response you need two CARDIODS back to back (one of
which is polarity reversed obviously).

Hi,
Seems likely then that the problem is related to the usual in
head problem that many (maybe even most) people people have with
simple, non matched HRTF based systems, whether driven from decoded
Ambisonic signals or from binaurally recorded (dummy head) material.
There's been a lot of
