AudioMoth
AudioMoth is a low-cost, full-spectrum acoustic logger, based on the Gecko processor range from Silicon Labs. Just like its namesake the moth, AudioMoth can listen at audible frequencies, well into ultrasonic frequencies. It is capable of recording uncompressed audio to microSD card at rates from 8,000 to 384,000 samples per second and can be converted into a full-spectrum USB microphone.

Underwater Case
The AudioMoth Underwater Case enables a standard AudioMoth to make recordings underwater. The case is designed specifically for AudioMoth version 1.2.0 (without the 3.5mm socket). Although other versions of AudioMoth will fit inside the case, we recommend version 1.2.0 to minimise self-noise in recordings. The case is made from injection-moulded polycarbonate and comes with an adjustable velcro strap, which makes securing AudioMoth simple and easy. The case is compact and highly resilient and will house AudioMoth for extended periods of time at depths of 30-60m.​
