Using the Echo Meter Touch 2 Pro plug-in module, available from www.wildlifeacoustics.com, Amazon, or through distributors worldwide, this app allows you to listen to, record, and automatically identify bats by their ultrasonic echolocation calls. The module and this companion app reveal the silent and often times invisible world of bats, providing outdoor enthusiasts, citizen scientists, and researchers an affordable and informative way to interact with these important creatures.
There in now only one available: Echo Meter Touch 2 (EMT2) has been discontinued for iOS and was intended for nature enthusiasts and batting hobbyists and Echo Meter Touch 2 Pro costs $349 and is designed for bat professionals and features a higher quality microphone, adjustable gain, and higher sample rate.
The Echo Meter Touch Ultrasonic Module senses ultrasonic signals, digitizes the signal, and transmits the ultrasonic data to the app on your iOS device. The EMT2 offers exclusive features and unprecedented ease-of-use for a handheld bat detector.
LISTEN TO BAT’S ECHOLOCATIONS
EMT2 translates bat echolocations into frequencies that are audible to humans using two technologies. Wildlife Acoustics’ patented Real Time Expansion (RTE) allows you to listen to bats in real time with unparalleled fidelity. RTE maintains the timing and tonality of the original echolocations. Heterodyne (HET) listening via manual and automatic tuning is also available, for those accustomed to that way of hearing bats.
VIEW THE ECHOLOCATIONS ON A SPECTROGRAM
A real-time spectrogram shows the frequencies and timing of the echolocations. Scroll back in time and zoom in on previous "bat passes."
SEE MOST LIKELY BAT SPECIES IN REAL-TIME***
The Auto ID feature analyzes the echolocation calls and suggests the two most likely bat species matches in real time. This is the same technology used in our professional Kaleidoscope Pro Bat Auto Identification software. Currently, the app can identify 26 species in North America, 25 in Europe and 57 in the neotropics. For more information on Kaleidoscope and a full list of species, visit our website.
RECORD .WAV FILES
Activate triggered recording mode to automatically save bat passes to full spectrum .wav files for analysis on a computer or to view on your iDevice. Or use manual record mode to control start and stop of recording. View the recording spectrogram and add voice or text notes. Listen to the recording using RTE, HET, or traditional Time Expansion Playback (playback at fractional speed to make the ultrasound audible).
SEE YOUR PATH AND RECORDING LOCATIONS
View in satellite or road map view. View identified species codes directly on the map. Go to the recording's spectrogram from the map view. Transfer to your computer to view in Google Earth. Your iDevice must have GPS capability or you must use a Bluetooth GPS receiver for this functionality.
*Continued use of GPS running in the background can dramatically decrease battery life.*
TRANSFER RECORDINGS TO YOUR COMPUTER
The EMT2 can transfer the .wav recordings to your computer over a Wi-Fi network or cabled through iTunes. Using Wi-Fi, the app bundles the recordings in a .zip folder and allows download by entering a URL in any web browser.
SHARE RECORDINGS VIA EMAIL OR MMS MESSAGING
And import and open files that have been shared with you.
***Because bats vary their echolocation calls in response to a wide variety of needs, no automated identification can achieve 100% accuracy in species identification. Auto-ID, though largely accurate, should not be relied on as a basis for scientific research. Auto-ID is intended for use in analyzing recordings of single bats in free flight in low clutter environments. Auto-ID will not work well on recordings of roost emergence, multiple or captive bats, bats in high clutter environments, or bat social calls. Auto-ID does not include every possible bat for each of the covered regions.
+Minor bug fixes.
Ratings and Reviews
As someone who enjoys bat-watching, I’m very happy that there is a fairly affordable bat-detector with an auto-ID feature. I just wish there were more phyllostomid representation in the auto-ID.
For the money required to play, this is only ok. Enjoy the bat info but gps tracks are unreliable/hit-miss(with updates it has gotten better). Understand technology is difficult to identify bats so I don’t fault app too much for Floridian bats in California. App/hardware just seems finicky in my opinion. I can’t simply “plug n play” reliably, something just goes wrong more often than not, especially with extension cord and/or extension piece required because of phone case. Will continue to use as I have already invested in the hardware, but I do hope continued updates improve performance. ‘Free’ analytical software for computer was not worth the effort required to set up (I’m not too computer savvy so I deleted it.)
If you have some extra money and enjoy the wonders of Mother Nature, check this system out.
This is an awesome device & I highly recommend it. I’ve been interested in bats for a long time & this is so educational! It’s so cool to show off to family & friends from my travels. My fave feature is the i.d. part where you put in the state your located & the different types are listed. Definitely worth the price & so fun to use:)
