Jim Peters wrote this open-source Binaural Beat Software. Here is what he says about the program. "SBAGEN is my utility, released as free software (under the GNU General Public License) 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."
