So there are tradeoffs between battery capacity and memory card space vs. recording length and recording quality. To have the most suitable settings for different periods of the day, I was wondering whether it would be possible to have different settings (sample rate, gain, sleep duration, recording duration) for each recording period to optimise battery and storage use while collecting information on different sound sources.
What I would want is one recording period for birds in the morning, a second, low frequency one during the day for anthropogenic sounds and a short very high frequency period in the evening for bats.
Is it possible to do that using the configuration app? Or is it something you are planning to implement for the next software release?
Thank you very much for your amazing work!
I agree the ability to modify recording parameters for bats/birds during the night/day would possibly the most useful feature for long-term monitoring purposes. It would potentially offer the biggest leap in managing battery/memory for continuous deployment, other than installing external batteries/memory systems.
Seems this thread has been running for a long time, but I would just add I too would really like to be able to specify settings for both birds and bats rather than leave two AudioMoths in the same location which is a bigger limitation on survey design.
I second all of that. We're about to deploy non-AudioMoth units in Cuba and the Dominican Republic in an incredibly remote area with limited access (military-controlled lands in the case of Cuba where our collaborators can't just come and go). Even though sunrise time doesn't change much at those latitudes, it changes enough so that we decided we couldn't use our AudioMoths for this project. For our case, we'd like the ability to record 30-minutes pre-sunrise to 30-minutes post sunrise every day.
Other nice addition to the software would be an option to schedule a recording period based on local sunrise and sunset time! Birds are most active on the first few hours after sunrise and a few hours before sunset. To achieve that it requires to update field configuration a few times in the season.
One quite simple way would be to manually specify a few (3-5) sunrise/sunset dates in Configuration app, so the app can calculate when to start (shift) each day’s recording. For example, Apr 01 – local Sunrise 06:51, local Sunset 20:03 and May 01 – Sunrise 05:34, Sunset 21:07. It’s 30 days apart and Sunrise became 1 hour and 17 minutes earlier, but Sunset - 1 hour and 4 minutes later. So every day till May 01 morning recordings will start (shift) 2 minutes and 34 seconds earlier, but each Evening recording will start 2 minutes and 8 seconds later.
‘Morning’ shift could affect all recordings in a period from 3 AM to 3 PM, but ‘Evening’ shift from 3 PM to 3 AM.
Has this suggested option of specific settings for different periods been implemented (I'm behind firmware upgrades because of https://www.openacousticdevices.info/support/device-support/audiomoth-1-0-0-not-recognized-with-firmware-1-4-4) ?
If not, is this option being considered for forthcoming versions of the apps? It would be so useful.
