Actually I suspect that 4 mikes is enough to establish a
soundfield and am quite sure that 16 would be.
That is for the soundfield impinging on one spot of course.
The four mikes would be four omnis in a spaced tetrahedron,
say 10 inches on a side.
I suggest that 4 omni-directional microphones, that close together. would
yield mono unless some precautions were taken to isolate the microphones from
each other (as in Kimber's Iso-Mike setup.
