This is a synthetic sound field that is generated through amplitude modulating a single audio sample. Three frequency layers, all sent through an FIR filter. It's possible to generate very believable sounding night ambiences with this. Crickets, locusts, frogs, aliens, Quakers? Check out the presets. the audio sample is a friend of mine saying the word "colour".
Very nice to listen to as an ambience when doing mundane things around the studio like paperwork or cabling.
Changing the replicator count from 3 to 2 should make this Pacarana sound Paca compatible. I have no idea whether this runs on a Capybara.
