An opensource binaural-beat generator. Gnaural is an opensource programmable auditory binaural-beat generator, implementing the principle as described in the October 1973 Scientific American article "Auditory Beats in the Brain" by Gerald Oster. The central theme of Oster's article was that processing of binaural beats involves different neural pathways than conventional hearing. Research inspired by the article went on to show that among other things, binaural beats could be used to induce a "frequency-following response" (FFR) in brainwave activity.

Gnaural can play sound directly through your computer sound system, or create a sound file that you can burn to CD or put on your iPod/MP3 player. Either way, you will need earphones to actually experience binaural beats, as the principle requires isolating the stimulus to each ear.

Gnaural was designed to be a multi-platform programmable binaural-beat generator, implementing the principle of binaural beats. A programmable binaural beat and pink noise generator. Outputs in stereo 44.1khz PCM WAV format.

Some random tips to get you started:
1. Double-clicking creates a new data point
2. Click-and-dragging across data points selects them
3. Add more to a selection by holding Shift and selecting more points. Likewise, subtract from a selection by holding Ctrl
4. Selected points can be moved en masse by dragging any single selected point
5. Use Shift with the Arrow keys to precisely move selected points
6. Pressing the Delete key deletes points, but not the time associated with them. To also delete time, press Shift-Delete
7. Ctrl-C, Ctrl-X, and Shift-X can copy selected data points. Ctrl-V will paste them
8. Delete (on your keyboard) will erase any selected data points. Shift-Delete will also delete the durations associated with the data points
9. Ctrl-Z will undo the previous operation; Ctrl-Y will redo
10. Dragging data-points beyond the right-edge of the graph will extend the duration of the schedule
11. Dragging data-points above the top edge with recalibrate the graph's scale to contain the point
12. Remember to press Ctrl-L ("Apply") after making changes to the graph; otherwise, they can't be saved or run in Gnaural
13. Your progress through a schedule is indicated by the green line on the graph; if you don't see a green line, it means you haven't pressed Ctrl-L since making changes
14. Paste (Ctrl-V) will paste the time BEFORE the clump of datapoints as well as the time they contain (so as to precisely place a pasted area over it's parent area)
