I could be wrong, but as I understand, as far as the distance between
the microphones is much smaller than
the wavelength, it is possible to obtain first-order microphones with
any kind of directional pattern. Thus,

THe Harman mems microphones presumably depend on their size, and
shape, to make them directional. They are not "two omnis and some
DSP" but "utilize an acoustical design to achieve directionality".
4mm wide is not too large, 22mm a bit more problematic. There seem to

Seems to confirm some of my speculations.
