Hello,

I have recently deployed an audiomoth near me to test whether it could detect and record bat and or bird calls.

I set it up so that it had a trigger of 1kHz as I dont want it to record human voices. But after a weekend of recording I have found that everything was recorded which resulted in recordings of 11 hours each day.

I have messed around and even changed the filter type to a band and to only trigger when it detects a sound above 20kHz and it still records human voice. Im guessing there is something I am missing.

So my question is, how do I set up the audiomoth using the configuration app to only record sounds above a certain frequency? And is there a way to set it so that when a trigger (for example, over 15kHz) it will record for 30 seconds and then stop until it has another trigger event? (Or does the trigger function mean that it will record any sound no matter the frequency once it hears the trigger?) I understand that this will mean that during a 11 hour period there may be many files created but that is what I want really.

So long story short, I want the audiomoth to do the following:

.Only record sounds above a set frequency (I do not want it recording human voices).

.I want it to start recording after a trigger and then only record for 30 seconds or so before stopping the recording. (It should then record for another 30 seconds after each trigger etc.).

Could someone help me with this please? Thank you
