I'm having trouble turning the integers in the .wav files from my AudioMoths into physical units. Could someone tell me the conversion constant for medium gain, and ideally other gain settings too? I've already looked at an AudioMoth datasheet, which gives the microphone sensitivity (V/Pa) and some info on pre-amp gains. But, I would need to know the ADC conversion constant (V/count) to finish the conversion, and I can't find that info anywhere (the Gecko datasheet says that several ADC configurations are possible and I couldn't figure out which one is used in the AudioMoth firmware). I'm really looking for a number in Pa/count that I can just multiply by the integers in the .wav file to get pressure units. Thanks for any help.
