The Audio in this video is a synthesized AUM at 136.1 Hz, created by Starseed's Bastian Jermutus.
This tone, roughly a C#, known as the "Earth Tone" or the "Om Tone" as transposed into an audible octave,
equals the frequency of the Earth's revolution once around the Sun.
This tone was originally determined by Swiss musicologist Hans Cousto.
