This companion app along with the Echo Meter Touch Ultrasonic Module ($399 direct from www.wildlifeacoustics.com or through distributors worldwide) allows you to listen to, record, and identify bats with your iPad, iPhone, or iPod Touch.
The Echo Meter Touch (EMT) Ultrasonic Module senses ultrasonic signals up to 128 kHz, digitizes the signal, and transmits the ultrasonic data to the iDevice via the Lightning connector.
The EMT offers unparalleled features in a handheld bat detector:
LISTEN TO BAT’S ECHOLOCATIONS
EMT 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 EMT 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 call identification can achieve 100% accuracy in species identification. Nevertheless, in the hands of well-trained experts, bat detector recordings can be used to identify many species, providing invaluable discoveries. The Echo Meter Touch allows high quality recording suitable for analysis by experts. The built-in Auto-ID feature also suggests the two most likely bat species for each recording, for the enjoyment of enthusiasts hoping to learn more about bats. These automated identifications, 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. Recordings of roost emergence, multiple or captive bats, bats in high clutter environments, or bat social calls are not suitable for Auto-ID. In addition, the Auto-ID feature does not include every possible bat for each of the covered regions. Therefore, if a bat that is not included is recorded, it will be identified by the app as a species with a similar echolocation call type.
