I had a conversation recently with a user testing the trial device regarding changing the default sampling rates selectable via the config software. They were keen to record at a sampling rate of 384Khz. I thought I'd therefore open a thread on the forum to allow the AudioMoth team to reply with a little more information regarding what's possible with the current device, as I believe at present 222KHz - 240KHz with short buffer recordings is the max to retain stability (and SD write speeds / cart types also need to be accounted for).
If you need another tested, let me know.
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.
Hi! I am from Osmania University, working on bats of Central and Western India, I wanted to know that can i select the range of recording to a specific frequency? like if i want to record only between 16kHz to 60kHz where i can get specific Vespertilionidae and Emballonuridae calls?
