I read an interesting article today about MEMS microphones, their small size and low current draw, and a host of other advantages over other microphone technologies.
The article was published on Hackster.io, an interesting site that showcases various manufacturers items.
Today’s article was about a MEMS stereo microphone board that plugs in via USB, and I thought it might be interesting.
You can read about it here:
They didn’t give a sensitivity fig. I’m actually trying a new mic (well it’s on my to do list anyway).
Carl has some accuracy challenges sitting on the floor recognizing words in grammar from a standing human speaking in normal home conversation levels.
I saw a far field array mic with 6 or 8 of these MEMS mics, but it doesn’t integrate well with Carl’s layout.
I was thinking that you could make a small hole on each side of Carl’s head.
I didn’t see a price either, though it looked interesting.
Perhaps there’s a different mic you could use?
