I seem to remember the Zylia uses Primo electret capsules. And this post on the Prorecording list seems to confirm it: https://www.tapatalk.com/groups/prorecordingworkshop/zylia-microphone-t19409070.html
And this AES publication confirms at least the electret part: http://www.aes.org/e-lib/browse.cfm?elib=17902 "Zamojski, Jakub Affiliation: Zylia sp. z o.o ... a spherical microphone based on inexpensive electret capsules" Op do 16 aug. 2018 om 20:33 schreef Stefan Schreiber <st...@mail.telepac.pt >: > I don’t believe at all that they (Zylia) are using MEMS clusters... > > Otherwise very interesting thoughts in the cited mail below... > > I also believe that noise of different capsules doesn’t add up (so I > agree with Bo-Erik, at least at first sight), but we can’t get below > the noise floor of a single capsule.
