@Alex Rogers Any word on the firmware triggered by bat calls?

If you need another tested, let me know.

@Alex Rogers Perfect! That's really what we needed. Thank you for the prompt reply!

Hello, I also would like a filter to limit recordings to bats. This option is standard in recorders for bats and greatly reduces the number of recordings to a few gb during a multiple night sampling interval. Even with the sleep for 5sec and record for 5sec options, which means data are never recorded, the cards fill up, which means data are never recorded and also take a long time to process. Ultimately, this means the audiomoths can't compete with commercial devices that capture the precise types of audio that we desire versus simply recording everything and making us try to get the calls we want from that enormous data swath. We don't have time in the back end to be worth the reduced cost.
