For clarification:
Could the eigenmike also do some 4th order recording (in a "real" sense,
not giving some 4th order "output"), or is it a 3rd order microphone?
Thanks,
Stefan

When the em32 Eigenmike was in prototype
form, mh acoustics promoted it as up to
fourth-order (although

with 32 capsules, the eigenmike is capable of measuring the full set of

When you go from the tight confines of a classical SoundField to a
general cloud of mics, there's not just one but three se

that's the main problem with the eigenmike: the higher the order, the
narrower the bandwidth and the higher the lower boundary. which means
that an eigenmike signal set will not usually be downwards-compatible

deriving low-frequency, high-order information from tightly packed
capsules (i.e. capsule distance small compared to wavelength) requires
ridiculous amounts of gain.
Yes. I referred to that as the A-to-B noise amplification problem within
the matrix.
The eigenmike is supplied with a software application called EigenStudio, which
allows the user to output various beams with selectable directivity. Those
outputs aren't, or mostly aren't spherical harmonics. Instead, one has
available cardioid, hypercardioid and supercardioid outputs up to 3r
