The following is a brainwave entrainment file I produced.
Disclaimer: I accept no liability for any ill-effects experienced by anyone who partakes in brainwave entrainment. Use discretion and continue at your own risk.
There are two tones being played, both with an isochonic beat of 7.83hz, the resonant frequency of the Earth’s ionosphere or “Schumann Resonance”. The tone in the left channel is five octaves above 7.83, which is 205.56hz. This is a resonant overtone of the primary Schumann frequency. The tone in the right channel is 405.41hz, which is 205.56 x Phi. Together the frequencies form a Golden Ratio harmonic binaural beat.
Enjoy and let me know what you think!
