Is audiomoth supposed to show the last configuration when connecting it to the computer again?

I've set up the audiomoth using the configuration desktop app, the schedule, recording frequency, everything i want, and then i click on "configure audiomoth". However, when i connect it back again to check it saved everything, it shows up blank, as if I connected it for the first time. The time however is saved normally. Is this supposed to happen and after I click "configure audiomoth" I'm supposed to just flip the switch to "Custom" and let it record and it will do as i specified? Or am I doing something wrong and its supposed to show the previous configuration?

Yes, this is supposed to happen. Flicking the switch to CUSTOM after clicking Configure AudioMoth will then start recording as specified. AudioMoth saves a CONFIG.txt file to the microSD card when the AudioMoth switch position changes from USB/OFF after configuration. This CONFIG.txt file can be used to check it saved everything correctly. The Config App does not read back the configuration from the AudioMoth. This is by design so that you can set up the Config App, and then plug in multiple devices in sequences to configure each one to the same configuration.

Is Standard GPS Time Setting Sufficient for Sub-Second Sync Across AudioMoth Devices?

Hi everyone,

I’m working with multiple AudioMoth Dev (with GPS) units and I need precise, synchronized recordings across devices.

Instead of using the GPS-Sync-Firmware, I am wondering if I can use the Standard Firmware 1.11 and the Configuration App. In the Configuration App I’ve enabled:

Enable GPS time setting: Yes
GPS fix before and after: Recording periods
GPS fix time (mins): 10

Thank you for the detailed explanation! I had missed the PDF, sorry.

If I understand correctly, the AudioMoth GPS Sync firmware consumes more power because the GPS remains continuously active, compared to using GPS with the Standard Firmware configuration. So, it’s essentially a trade-off between timing accuracy and power consumption, is that correct?

dBFS transformation to dBA

Does know of a step-by-step process for converting dBFS recorded on AM's to dBA? I have the frequency band breakdown for each recodrded file and had Moths set with low gain and a 48kHz sample rate (not sure if these factors are relevant). Thanks in advance...hopefully!

We hadn't thought of doing but we could consider it. AudioMoth tends to get deployed in a range of different housings, so those would need to be calibrated in order order to give meaningful values.
