Using AudioMoth with Filtering and Amplitude Threshold Recording

01/06/2020

The most recent versions of the AudioMoth firmware (version 1.4.0) and configuration app (version 1.3.0) introduce two new functionalities: the ability to apply low-pass, band-pass or high-pass filters on the device, and the ability to reduce recorded file size by applying an amplitude threshold.

An injection moulded case for AudioMoth

21/05/2020

While lightweight ziplock bags can be used to deploy AudioMoth for short periods of time in mild conditions there is a clear need for a more robust solution for long-term deployments. To address this need we have developed a waterproof injection moulded case specifically designed for AudioMoth.

AudioMoth Temperature Measurement

05/06/2020

The AudioMoth micro-controller contains a factory-calibrated temperature sensor. This sensor has not  been used in previous versions of the AudioMoth firmware. However, version 1.4.0 adds a temperature measurement at the start of each recording with the results written to the comments section of the WAV file header.
