AudioMoth is an open source full-spectrum acoustic logger built around the Silicon Labs Gecko processor by the Open Acoustic Devices Team. It can detect sound from ranging from audible to ultrasonic frequencies and can record uncompressed audio to micro SD card from 8,000 to 384,000 samples per second. A popular research tool for environmental and biodiversity researchers worldwide thanks to the Arribada Initiative, you can now find unattended AudioMoths in some very unexpected places such as rain forests, jungles, and bat caves worldwide.

AudioMoth Configuration App
The AudioMoth configuration app is an easy to use tool for customising your AudioMoth logging devices.
Using it you can schedule recording periods, customize recording gain and sample rates as well as calculate approximate device lifespans given a configuration.
The app is available for download here on the Open Acoustic Devices website, as well as more info.
