Hello,I would like to make some stereo recordings using two audiomoth devices and I would like to know what is the mem microphone polar pattern. Is it omni, cardioid, directional...?I really apprecite any information.Thanks in advance
According Directivity specifications from the datacheet you have linked it is "Omni‐directional". Is this the mem mic used by Audiomoth?
I haven't seen any measured directional sensitivity plots for the actual microphone used but most MEMS microphones claim to be omni-directional.
As part of our trials with the Bat Conservation Trust we did some directional tests of the sensitivity to bat calls and I'll post up a link to the report shortly.
