The Echo Meter Touch Bat Detector is an Android app that allows you to listen, record, and identify bats by their ultrasonic echolocation calls. The app is designed to work with Echo Meter Touch 2 plug-in modules, which sense ultrasonic signals, digitize the signal, and transmit the ultrasonic data to your Android device. The app, along with the modules, provides outdoor enthusiasts, citizen scientists, and researchers an affordable and informative way to interact with these important creatures.

The app offers exclusive features and unprecedented ease-of-use for a handheld bat detector. It translates bat echolocations into frequencies that are audible to humans using two technologies: Wildlife Acoustics’ patented Real Time Expansion (RTE) and Heterodyne (HET) listening via manual and automatic tuning. A real-time spectrogram shows the frequencies and timing of the echolocations, and the Auto ID feature analyzes the echolocation calls and suggests the two most likely bat species matches in real time. The app can identify 26 species in North America, 25 in Europe, and 57 in the neotropics. You can activate triggered recording mode to automatically save bat passes to full spectrum .wav files for analysis on a computer or to view on your Android device.
