Currently working on a project that involves recording bat audio in urban environments. I had configured and flashed with some configs that seems to have worked in the past (from other posts), but I think the Issue I am having is related to the filtering. I did a test recording and it didn't really seem to filter anything out when I had set it to amplitude 20kHz -96kHz. For trigger duration I dont exactly remember what I did but I believe that it was at zero seconds which is definately an error and I'm not really sure what Amplitude durration means and if I should touch that when setting a filter. I'll list my configurations for some context Sample Rate: 192 Gain: Medium Enable sleep/record cyclic recording: on Sleep duration: 5 Seconds Recording duration: 55 seconds Schedule 7:00 pm - 12:00am Trigger Type: Amplitude Filter Type: Band (20khz - 96khz) Minimum Trigger Duration: 0s Amplitude Threshold:? Could anyone provide some insight in which configuration settings I should have? For some additional context, I mainly want to investigate bat biodiversity in urban environments and their feeding guilds for different sites with varying vegetation.
