I looked at microphones and many projects seem to use similar variants: Warning - too much detail might be incoming: if my notes are correct- pippyg uses SPV0142LR5H-1 microphone; Audiomoth uses SPM0408LE5H microphone; something else uses SPU0410LR5H microphone. These microphones all seem to be rated up to 20kHz but the data sheet shows them testing up to 80kHz. I have no idea what the differences between them are however!
