Yes. If you use the GPS board with the AudioMoth, then clocks will typically be synchronised to within a few milliseconds (depending on how the GPS syncs are scheduled).

Great paper that uses @openacousticdevices.info AudioMoth and neural network models to record and analyse the ultrasonic calls of wild mice.

It’s hard to find a nice small monitor these days. This twenty-year-old 17” Apple Studio Display is perfect though for my office Mac Mini server.

We found that SanDisk Ultra 256 GB cards use a lot more energy than most other cards. I'd recommend SanDisk Extreme cards. www.openacousticdevices.info/sd-card-guide

Can you post the details on the forum here - www.openacousticdevices.info. What make and model of SD card, and battery, are you using,

We have an external microphone and waterproof mount coming out soon which might work well for this application. The electret capsule microphone is a little less noisy than the internal MEMS microphone.

Our github Repo for the Mothbox is getting pretty big: github.com/Digital-Natu...

it has the Hardware, Firmware, Documentation Website, and Post Processing Software all on there.

This is nice for us as i can send a single pointer to folks about the Mothbox. But should i organize it different?
