I've put together a sounds track made up from some of the strangest/oddest recordings ever made.
The track includes:
-Mongolian throat singing, where 2 notes are produced at the same time
-Upsweep is the name of a recording made by the US's secretive underwater recording system known as SOSUS (SOund SUrveillence System). SOSUS is a network of unknown extent stretching throughout the oceans of the world and constantly recording sounds. Designed by the military for tracking submarines etc.
The recording is of an ongoing sound of unknown origin. Mostly emanating from the centre of the Pacific, it may be volcanic activity or tectonic. Although it changes in sync with the seasons.
