The EMT 1 and EMT 2 Pro can be configured to record sounds above 8 kHz other than bat echolocation pulses, such as mice vocalizations. Because the EMT settings are tuned by default to automatically record bats, a few settings changes are necessary.
In the advanced settings pane, turn "Real-Time Auto ID" off to prevent the app from trying to assign a bat species to your recordings. Turn "Save Noise Files" on so that recordings will be kept regardless of if the app thinks it recorded a bat or not.
When you are in live mode, using the manual record button to create continuous recordings may be more useful than using the automatic, triggered recording mode, which is tuned for bats and may perform ideally with non-bat vocalizations.
