AudioMoth GPS Sync

Audiomoth GPS Sync allows AudioMoth to make audio recordings that are precisely synchronised against GPS time. It consists of custom device firmware that generates standard unsynchronised WAV files along with a custom CSV file containing synchronisation information. A desktop app uses these files to generate synchronised WAV files that are aligned with GPS time to better than 1 microsecond.

To use the firmware, download it from here:

AudioMoth-GPS-Sync-1.0.0.bin

The firmware downloaded above should be written to the AudioMoth using the Local File option within the AudioMoth Flash App. You can revert to the standard AudioMoth firmware at any stage using the Standard Release option.

The desktop app can be downloaded below:

Current version: 1.0.0

macOS

Windows

64-bit Linux

See the application note here for the full details on how to use this custom firmware.

Rather than using a configuration app, the firmware reads its settings from a SETTINGS.TXT file on the SD card. There is an example SETTINGS.TXT file here.

Note that this firmware requires that an AudioMoth GPS Board (or equivalent) is connected to the AudioMoth.
