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.
Hi Alex, Thank you for posting several of these posts explaining how to use the two types of AM filtering, something I’m going to be trying (for bats).
So I wanted confirm something about scheduling and triggering. Let’s say I configured my AM to trigger based on amplitude using the settings you shared in this post. But let’s say I also configured the device for a Sunset to Sunrise schedule. Does this mean that the AM will only record amplitude triggers occurring during the Sunset to Sunrise period (= the settings are cumulative/additive rather than somehow separate)? I assumed that’s how it works, but just wanted to confirm 😊
