Hemisync is "binaural beat" brainwave technology. It is a kind of meditation & brain enhancement tool, where you listen to electronically generated sounds with a pair of stereo headphones.
There is also Holosync and a free program called "bwgen" (brainwave generator), which do the same thing.
How it works is that it plays different frequencies into the left and right ear. The brain takes these separate frequencies and integrates them into a single perceived carrier tone - a binaural beat. What this does is cause both hemispheres of the brain to work together, and with repeated use, new neural pathways between the left and right brain will be formed - a process known as "entrainment". This results in:
...communication between parts of the brain that previously were not communicating, or were communicating only a minor amount. One of the unique things about the Holosync® technology is its ability to create synchronisation between the two hemispheres of the brain, over time making this kind of cross-hemispheric communication permanent.
This increase in communication within the brain leads over time to what scientists call whole brain thinking or whole brain functioning. This includes such things as increased learning ability, creativity, intuition, mental clarity, and intelligence, plus an increase in what some would call "mystical" or "metaphysical" powers -- in my opinion, latent abilities we all have but usually do not exhibit because we use such a small portion of our brains.
But here's the really amazing thing that happens: every time the nervous system makes a quantum leap -- every time your brain reorganise s in response to the input we are giving it with the Holosync® technology -- in order to make that shift you have to let go of some of the unresolved mental and emotional material we all have under the surface in the unconscious mind. Whether it is unresolved fear, anger, anxiety, sadness, or limiting beliefs, some of this material will be incompatible with the brain's ability to operate at the next higher level of functioning and will be resolved.
I used to be an active participator on the Holosync forum, because my plan was to use binaural beat technology and nootropics together. This could make a quantum leap in intelligence and brain function. I still intend to do so, when I am ready. But the Holosync CDs are very expensive. There are free Hemisync downloads on P2P file-sharing networks, but they are in lossy MP3 format, and I would rather work with an integrated package than just listen to some random MP3s.
I am just sharing what I know about this technology. Here are a couple of links that may help to explain more:
