A programmable binaural-beat audio generator
Gnaural is a programmable "binaural beat generator", based on the
principle first described in October 1973 Scientific American, Gerald
Oster, Auditory Beats in the Brain. There has been considerable
research done on this principle since that publication, and Gnaural's
predecessor, WinAural, has even been used as the audio stimulus
in a study published in the proceedings of Biomedical Engineering
2004, "The Induced Rhythmic Oscillations of Neural Activity in the
Human Brain", D. Cvetkovic, D. Djuwari, I. Cosic (Australia), From
Proceeding (417) Biomedical Engineering - 2004.
The central idea of the Binaural Beat principle is that brain activity can
be entrained to the auditory beat frequencies created when each ear
is presented simultaneously with tones of slightly-differing frequency.
It has been proposed that entrainment can be used to target specific
mental states, ranging from restful and meditative to highly alert.
Gnaural can output directly to your computer's soundsystem, or to an
audio file (.WAV format), which you can then burn to an audio CD or
compress to MP3 to make available for portable use. Stereo
headphones are required to maintain the stereo separation of the
tones needed for your auditory system to create the binaural beats.
