ECHO METER TOUCH 2 FOR iOS

Overview

Learn about Bats

Echo Meter Touch 2 can identify the most likely species of bats in your area.

There are thousands of bat species in the world, each with its own slightly different type of echolocation call. Every time you watch for a bat, Echo Meter Touch listens for it and processes the sound using highly complex, proprietary algorithms called “classifiers”. In a split second, Echo Meter Touch shows you the most likely species of bat flying overhead. You can click on each species to learn more. Currently, Echo Meter Touch can identify bat species from North America, the Neotropics, the U.K., Europe and South Africa. Full List

Hear Ultrasonic Bat Calls

Discover the world of ultrasonic sound.

Bat echolocation calls are ultrasonic – out of the range of human hearing. The Echo Meter Touch combines a special microphone with sophisticated circuitry and software to transform ultrasonic bats calls into audio that you can hear. Echo Meter Touch displays the bat calls on an interactive, scientific-level spectrogram. You can pause the audio, zoom in on each recording, and listen to it in more detail using one of three professional-level listening modes: Real-Time Expansion, heterodyne, and post-recording time expansion.
