You are  listening to a 40 second excerpt from "Drumming - Space Fold" by Tom Tuduc - This section contains traditional pure binaural beats of  7.83 hz or the resonance of the Earth - also known as Schumann resonance. An average session is 6-20 minutes long and has the effect of being in nature.

This is a demonstration.  OmHolo sessions use modern techniques such as filter modulation, monaural, and pulse, to produce less intrusive audio.
