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

I have found some information about the highend frequency but have not found anything clear about the range. Can audiomoth record from 20hz to 20Khz? Can I conect an external electret microphone? Has audiomoth plugin power capabilities? And, when it will be again avaible? Thaks Xoán
