1. If you want to experience bat sounds during the daytime, in a classroom environment, or when there aren't any bats around, just turn on Demo Mode in the Bat Detector section of the settings App, and Bat Detector will loop through a collection of bat recordings from Wiltshire, England.
2. These are not the recordings of the sounds you hear coming from the detector, but are the sounds going INTO the detector - the true ultrasonic sounds that the bats made, too high for humans to hear.
3. However, operating in true real-time means that the rhythm of the bats calls is preserved, and heterodyned bat sounds - despite sounding nothing like bats - are diagnostic and distinctive, so heterodyning remains an invaluable tool for all bat workers and enthusiasts.
4. The heterodyne process then turns any bats sounds it hears into percussive cracks, pops and slaps, or in the specific case of leaf-nosed bats such as Horseshoe species, strange alien warbles.
5. They are sounds synthesised by bat detectors using bat sounds as a source - rhe harmonic content of heterodyned sounds is distorted and mangled, and these sounds bear literally no relationship to the sounds the bats actually made.
6. All European bats and most of the world's "microbats" navigate, hunt and communicate using ultrasonic sounds, too high-pitched for human hearing.
7. Bat Detector reveals those sounds to human ears, and has two different methods to make ultrasonic bat sounds audible.
8. When "RECORD" is engaged Bat Detector will trigger a 5 second full-spectrum recording at 384kHz whenever it hears a bat, or at least something that it *thinks* sounds like a bat.
9. Firstly it brings the bat sounds down to an easy range for human hearing, the sounds generated by Bat Detector range from between 1kHz to just under 7kHz.
10. Heterodyning is a simple process that operates in true real-time, demodulating the bat sounds with a carrier signal just like an old transistor radio.
11. Most heterodyne bat detectors require you to manually tune into different species, but Bat Detector operates without any manual tuning, instead it tunes into the strongest bat signal it can hear.
