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.

Hi Steven,

thanks for the additional information!

as the sphere gets bigger the high frequency accuracy
gets worse.

In the Ambisonics case, but not necessarily always:

(Still nobody seems to take some care to explain how Nokia's 8-channel 3D microphone is supposed to work....

Not releasing (necessary) specs or functional information treats your (professional) customer as an idiot.


Best,

Stefan

Just to remember some former discussion (about Nokia's Ozo mike):

The MEMS capsules mounted on some sphere will show some cardioid response
at higher frequencies, but not at LF.

To judge the results anybody can compare  this "CE mike" with some "real
mike" later...

Best,

Stefan

They have an article (a first installment that doesn't say much) on their
site too. Its how to build an ambisonic mic for less than $99, using 4
omni
mems capsules??

Zokm already have done an update to the H2n that allows horizontal
ambisonics,  but that has 5 mics built in.  I take mine with me
everywhere.
It isn't great but extremely handy and light.  Got it so cheap that I'm
not
so bothered when i accidentally drop it either...

cor! terrible advert! I don't know what I'm supposed to learn from that!
love the idea of having something really mobile though. I had a dream a
couple of days ago that Zoom had made a new ambisonic mic for my Zoom H6.

Another mobile ambisonic solution, is this for real?

The claims just go on...
