We've just released a new web app as part of AudioMoth Labs. Using this tool you can explore filter and amplitude threshold settings on existing AudioMoth recordings before applying them on your AudioMoth in the field.
The Chrome browser allows you to load AudioMoth files directly from your computer. If you have not yet installed Chrome, you can still try out the AudioMoth Filter Playground by selecting one of the provided example files.
Once you have a configuration you're happy with, export it to a .config file which can be loaded by the AudioMoth Configuration App. Alternatively, export the displayed plots at any time by clicking the camera button in the bottom left.
