SD23 Bat Echolocation

DESCRIPTION: 

• 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 the feeding buzz of bats on the hunt. Hear a batnado as millions of Mexican free-tailed bats exit their cave and swarm with starling-like murmurations.
  
• 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. 

DEMO:

• 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 other than the BATNADO swarm from 3:00 to end.

KEY FEATURES:

• Swarming BATNADO of millions of Mexican free-tailed bats
• laser-like chirps
• resonant pings
• powerful searching clicks
• single bats and duets
• feeding buzz: accelerating attack clicks
• Most included files are above the range of human hearing. So they must be varispeed pitch shifted to be used for sound design.
• I recommend -60% to -98% varispeed pitch shifting.
• Ultrasonic bat echolocation clicks ranging from 20 kHz to 90 kHz
• North American bat species from 5 different locations

FILE LIST:

• Click "View larger version" in the bottom right corner of the File List below to open in a new tab for easier viewing. This works best on a desktop computer. 
• View spectrograms for each track, search, and filter in the Airtable spreadsheet. 

LIBRARY INFO:

• I recommend -50% to -98% varispeed pitch shifting for sound design usage. Therefore, the 38 minutes of included sounds functions as a much larger collection of 2+ hours of material.
