SD23 Bat Echolocation

Regular price $59.00 USD




  • In Bat Echolocation, get a collection of unheard sounds from North American bats. Hear powerful clicks that sound like alien languages and musical pings that ring for ages. Hear laser-like chirps and dancing duets of several bats hunting for their dinner.
  • This library offers you a collection of sounds not normally heard by human hears. With a little pitch shifting, this ultrasonic world is at your fingertips. I find unheard sounds fascinating, I hope you enjoy them too. Thanks for listening. 


  • This demo is made up of pitch shifted sounds. Otherwise you would not be able to hear them :)
  • All sounds included in library are ultrasonic.
  • Coming soon!


  • All included files are above the range of human hearing. So they must be varispeed pitch shifted to be used for sound design.
  • Ultrasonic bat echolocation clicks ranging from 20 kHz to 90 kHz
  • laser-like chirps
  • resonant pings
  • powerful clicks
  • single bats and duets
  • accelerating attack clicks
  • North American bat species
