So I harvested a mems mic out of a set of head phones with talkback facility, its the simple 2 wire analog connection .
How would I design a valve input stage with the required voltage for capsule power at the grid and maybe very high input impedance to maximise voltage swing from the capsule ,would a cathode follower work well here ?
Also Ive looked a bit at array microphones, is there any simple way of implementing a beam former from individual mems mics ,or does it all require computer processing at the back end to make it work ?
