The only Android based bat detectors on the market have received a major upgrade just in time for National Bat Appreciation Day, April 17, 2018. Users of the Android Echo Meter Touch 2 (EMT 2) and Echo Meter Touch 2 PRO (EMT 2 PRO) plug-in modules will now have several new functions, while EMT 2 users will also get access to several functions previously only available to EMT 2 PRO users.

Among the new functions that will be available to Android EMT 2 and EMT 2 PRO users via upgrade of its companion app is the ability to save recordings to an external SD card. Additionally, users will now be able to export files via Wi-Fi, filter out extraneous noise while listening for bats, and custom label recordings.

EMT 2 users will also get access to more advanced settings, previously only available to EMT 2 PRO users including audio division ratio settings to customize audio playback, the ability to save non-bat noise files, and turn on or off Nightly Session Mode and Auto-ID.

“The EMT 2 has made the world of bats accessible to virtually anyone,” said Sherwood Snyder, director of product management at Wildlife Acoustics. “We are constantly looking for ways to improve our apps and these updates give users ever more powerful tools to explore their interactions with bats.”

Nightly Session Mode is set as a default to off and allows users to organize listening sessions on a noon to noon basis organizing the recordings into a single folder as opposed to individual folders for each time recording is started and stopped.

Auto-ID by default is turned on and displays the bat species immediately following the conclusion of a recording. By turning it off users can listen uninterrupted and review and identify recordings at a later date.

Along with the new version of the app, the company released a firmware update of for the EMT 2 PRO improving its compatibility with some Android devices.

Previously, bats could only be heard and identified by using expensive scientific equipment, often costing thousands of dollars. Echo Meter Touch gives outdoor enthusiasts, citizen scientists, and researchers not only an affordable option, but one that offers equivalent or better recording quality.

The Echo Meter Touch module connects to Android devices via its USB connector. The module’s acoustical horn captures the bat’s ultrasonic calls and efficiently directs them to a highly sensitive microphone. The calls are then digitized and played back in real-time in audible sounds through the smartphone’s speakers with a full-color spectrogram on-screen. The app then automatically reveals the most likely species recorded. Each recording is tagged with the species and geolocation and can be shared with other bat enthusiasts or transferred to a computer for additional analysis.

Echo Meter Touch 2 ($179) is designed for budget-minded nature enthusiasts and batting hobbyists. The Echo Meter Touch 2 Pro ($349) is designed for bat professionals with a better microphone and has advanced features including adjustable microphone gain to better detect distant or quiet bats and a selectable sample rate to record bats with very high frequency calls.

National Bat Appreciation Day occurs annually on April 17th as April is when many bats begin to emerge from hibernation. Bat play a crucial role in our ecosystems by controlling insect populations and pollinating flowers. A 2011 study estimated that bats have an economic impact of about $23 billion a year in reduced crop damage and pesticide use in the United States.

iPhone and iPad users can expect a similar update to the Echo Meter Touch iOS app in the coming months.
