Accessories for AudioMoth

Founding developers Alex Rogers, Andrew Hill, Peter Prince

The AudioMoth was created by two computer science PhD students at the University of Southampton, Andrew Hill and Peter Prince, together with Alex Rogers, a computer science professor at the University of Oxford. The AudioMoth is the first product of their OpenAcousticDevices initiative.

AudioMoth is a low-cost, open-source acoustic monitoring device used for monitoring wildlife. AudioMoth is not only sensitive to audible sounds but well into ultrasonic frequencies. It records uncompressed audio onto a micro SD card from 8,000 to 384,000 samples per second.

AudioMoth units can be programmed to monitor wildlife populations by recording the calls of specific target species. Furthermore, it can serve as an alert system detecting sounds of human exploitation, such as the blast of a shotgun or the roar of a chainsaw.
