we've having troubles with an audiomoth device which has already the latest version of the firmware. The device register audio files but when I open them I hear only noises
Hi, It sounds like the microphone has suffered some moisture damage. Try recording you normal speaking voice about 0.5m away from the AudioMoth. Can you share an example of the WAV file. Alex
Yes, this seems to be water damage to the microphone. The AudioMoth would still be useable with an external microphone. It's also possible to change the microphone if you have access to an experienced electronics shop. However, it often isn't cost effective to do so.
