I have recorded bats in a cave at 192kHz using Sennheiser 8000 microphones.
The first part of the clip is the sound that I heard on location (bat wings and drops inside the cave)
The second part of the clip is the same sound that has been pitched down two octaves (removal of bat wings and drops)
The third part of the clip is the same sound pitched down 2.5 octaves.
The fourth part of the clip is the same sound pitched down 3 octaves.
The fifth part of the clip is the same sound pitched down 4 octaves.
By using this pitching process, we can hear the bats « singing ». We can hear the ultrasounds.
These are monkeys songs and yells recorded in captivity.
