Hi, I am writing about the same topic. The background noise is always high on the audiomoth v1.2.0 recordings, but I can hear my whistling (higher frequencies) through the noise (file attached). It happened to my 1.1.0 version already after 3 years of use but this time this is a recently purchased v.1.2.0, protected by a case this time, that ceased to properly work...

Any feedback appreciated.

Tony

Hola! Alex. Podrías comentar como agregar un icrófono externo al AudioMoth, por favor? Tengo el mismo problema que Marco.

The Application Note here -

- describes the connections. You can either solder directly to the pads on the top of the AudioMoth or use the 3.5mm socket -

Also, contact sales@openacousticdevices.info if you need sockets.

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.
