"BrainWave Generator generates binaural beats that change your brain frequency towards the desired state, be it relaxation or enhanced attention. In addition to using the more than 20 built-in brain wave entrainment programs, you can create your own programs (presets)."

"Binaural beats" refers to the technique of presenting your right & left ears with tones of different frequencies to generate simulated brainwaves.

States of mind included with the Brain Wave Generator software:

Delta: Deep sleep

BrainWave Generator

Some of the suggested uses for this software are meditation, quitting smoking, quitting drinking, or losing weight. In college I found other benefits...

I was at a friend's place in 1992 and was feeling very ill from having consumed too much alcohol. He handed me headphones connected to his PC, and all I heard was this weird throbbing hissing sound. About 15 minutes later I felt refreshed as if I had slept for hours. I used to make cassette tapes with binaural beats recorded on them to refresh myself between classes, to help fix morning hangovers, or before job interviews. This stuff really works!
