Hemi-sync was pioneered by the great mind and out-of-body researcher Robert Monroe. The binaural beat technology field now has several companies involved, but Robert was the pioneer who brought it into the mainstream.
Hemi-Sync helps you safely alter your brainwaves with multi-layered patterns of sound frequencies. When you hear these through stereo headphones or speakers, your brain responds by producing a third sound (called a binaural beat) that encourages the desired brainwave activity. With Hemi-Sync you can safely alter your brainwave patterns and experience enhanced mental, physical, and emotional states.
These topographic brainwave maps illustrate the state-changing potential of the Hemi-Sync process:
