Hi,
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
be some other components on what is presumably a PCB.
This makes it difficult to mount several in an array. Two, back to
back, might make some sort of figure-8 and a first order ambisonic
mic may be feasible, but beyond that ??
Ciao,
Dave

Yes of course, and as the sphere gets bigger the high frequency
accuracy
gets worse.
If you look at the mems with the pcb they are on, they look pretty
big.
For those that are interested, Harmon now make cardiod mems. They
won't
release spec though, unless one puts in a massive order. I already
enquired
about this chicken and egg. Unfortunately no go, unless i buy
thousands,
and sign NDA.

Interesting:

But those cardoid mems are not small...

And the cardiod mems are actually two omnis and some dsp !
