My audio moth appears to have continuous white noise and volume of recording appears to have reduced. I have changed the batteries, without any improvement, haven't tried filtering etc, as I never had to previously but I attach a test file - recorded in my bedroom, no case and speaking quite strongly into the microphone from around 300mm. Any advice would be welcomed (Audiomoth 1.1.0).

Hello, I had the same problem. I related it to a thunderbolt or maybe with the end of the microphone's useful life. In any case, the operation of the audiomoth is the same that you indicate, and I have not been able to solve it. I understand that the solution is to change the microphone, although my device recorded at a lower volume than yours
Best regards,
Eugenio
