I know very little about AudioMoth and the operational software. I would like to ask a question to people in the know. Is it possible to set the AudioMoth 20 Hz to 20 kHz with a 60 db (normal conversation) trigger threshold?

Yes, it's possible to configure an AudioMoth to record within a frequency range of 20 Hz to 20 kHz and set a specific trigger threshold, such as 60 dB. Here's how you can do it:
Steps to Configure the AudioMoth:
AudioMoth Configuration App:
Download and install the AudioMoth Configuration App on your computer.
Set Frequency Range:
Connect your AudioMoth to the computer and launch the configuration app.
You can configure the frequency range for recording. The default range typically includes 20 Hz to 20 kHz, but you should confirm this in the app settings.
Set the Trigger Threshold:

In the configuration app, you can set the "Trigger Level" under the "Audio Settings" tab.
The trigger threshold is usually adjustable in dB (decibels). If you want it to trigger at a normal conversation level (around 60 dB), you can set the trigger level accordingly.
Save the Configuration:
Once you've set the desired frequency range and trigger threshold, save the configuration to the device.
Deploy the AudioMoth:
After configuration, deploy the AudioMoth in the environment you want to monitor.
Yes. You can record at 48kHz and use an amplitude trigger to only record when the amplitude passes a set threshold. See the application not below: https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Using_AudioMoth_with_Filtered_and_Triggered_Recordings/Using_AudioMoth_with_Filtering_and_Triggered_Recordings.pdf
If you have some AudioMoth recordings you can try out potential amplitude trigger settings in the AudioMoth Play web-app (https://play.openacousticdevices.info).
