Binaural-Beats-1
This seems fun to play around with, even if it doesn’t do anything…Jim writes – “The theory behind binaural beats is that if you apply slightly different frequency sine waves to each ear, a beating affect is created in the brain itself, due to the brain’s internal wiring. If, in the presence of these tones, you relax and let your mind go, your mind will naturally synchronize with the beat frequency…SBAGEN is my utility, released as freeware (under the GNU General Public Licence) for Linux, Windows, DOS and Mac OS X, that generates binaural tones in real-time according to a 24-hour programmed sequence read from a file. It can also be used to play a sequence on demand, rather than according to the clock, or to write a WAV file for playing later. “ [via] – Link.
