Re: [Sursound] Multiple ambisonic microphone array?
Hello, The attached papers of mine may be relevant to your question. PCMA, a surround mic technique I proposed and evaluated in the papers does not use multiple ambisonic microphones, but uses 5 pairs of coincident microphones arranged in a spaced array. The purpose is to control perceived front-back perspective (zoom in/out) creating a virtual microphone with a different polar pattern and direction at each pickup point. (see Figure 3 in the 2011 paper). The same technique can be used for surround recording with height (the secondary mic in each pair captures more ambience than direct sound and is therefore routed to a height channel for spatial impression). Hope this is useful.

We've recommended using multiple TetraMics in spaced arrays to our customers many times, and we mention it on our web site. Perhaps the simplest is an ORTF array, decoding two TetraMics physically spaced 17 cm apart, and each decoded to cardioids angled to an included angle between them of 110 degrees. There's no reason this technique can't be used with other spaced array configurations. Then there's the much more complex possibility of using many TetraMics, uniformly distributed around a space, each dynamically tracking sound sources, and interpolating (handing off) between them as sound sources move around in the space.

Re: [Sursound] Multiple ambisonic microphone array?
I've rather simplistically used 3xSF mics, in a line, spaced approx. 25m (between no.1 and no.2 - hence spacing between 1 and 3 is 50m) to record adjacent 'cells', for replay in reciprocal fashion. The recorded venue was a choir in a cathedral, the replay in a large (but smaller than the cathedral!) foyer in the University. Visitors could then enter the 'virtual cathedral', move through the audience space, through the choir, out the other side - and the transformation of direct-to-indirect energy ratio was perceived appropriately for ambulant listeners, yielding appropriate changes in range perception as one approached sources. The odd local peculiarity due to precedence effects, but generally, the overall impressions were of a virtual space that one could move about in.
