Description

Echo Meter Touch 2, plug-in modules for iPhone, iPad, or iPod Touch allow the user to listen to, record, and automatically identify bats by their ultrasonic echolocation calls. The modules and this companion iOS 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 are two models available, either directly from www.wildlifeacoustics.com, or through distributors worldwide. Echo Meter Touch 2 (EMT2) costs $179 and is intended for nature enthusiasts and batting hobbyists. The Pro version (EMT2 Pro) costs $349 and is designed for bat professionals and features a higher quality microphone, adjustable gain, higher sample rate, as well as advanced settings.

The Echo Meter Touch Ultrasonic Modules sense ultrasonic signals, digitize the signal, and transmit the ultrasonic data to your 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.

What’s New

Version 2.5

+The iOS app replaces Open GL graphics processing with Apple's newer Metal processing. This is for future compatibility but also might improve performance on older devices.
+Deals more intelligently with recordings placed into the iOS file system. If EMT recordings are present, the app will offer to import them into the recording list. If other recorder's recordings are present they will be ignored.
+Fixes an issue where the spectrogram would fail to update when going from expanded to compressed view.

Opens a door to another world

I have to say that as an amateur naturalist I have been just delighted with this app and the Echo Meter Touch. Combined they allow easy access to the complex world of bats and helps you to start to understanding how very little we generally know about these amazing creatures. To have the ability to not only record the echolocation ‘shouts’ of bats but to also potentially Identify the likely species flying overhead in the dark is amazing. To then be able to play back the sounds and the sonograms for closer analysis is priceless in my book. However, to see the look of surprise and dropped jaws on folks faces when they hear these calls in such detail for the first time, especially youngsters, just goes to demonstrate how powerful this app and the Echo Meter Touch as educational tools and conservation motivators. I have already joined the local bat group and the Bat Conservation Monitor Group as a result of using the app. Here is the perfect vehicle for reinforcing the power and influence of citizen science. I just wish that I could stretch to the pro version.

Excellent kit.

The box of tricks arrived two days before I was due to go on holiday. I had very little time to get acquainted with the app. I need not have worried it worked perfectly. I spent every night close to Bodmin moor (in Cornwall) for a week collecting data with four spices of bat being identified. Can’t wait to get back home to examine the data on my computer. Having built many bat detectors over the years I now have a system that is a quantum leap over anything that went before.

Highly recommended

After using a traditional low priced bat detector in the U.K. for a few years I find this App is brilliant. Whereas before I could only say 'yes, there's a bat', this App offers solid suggestions as to what it's likely to be. I've already discovered I have 3 species visiting my urban garden. Absolutely ideal for amateurs, and well worth the outlay for the microphone (about £200).

Only reason I haven't given it 5 stars is that I can't find a way to load my recordings direct to Google Drive. That would be the icing on the cake <hint hint>
