Binaural Brainwave Stimulator 4.0 16 color strobe sets 300 Options (BrainStimPro) is a Professional Medical Brainwave Tuning tool for medical personal, Using adjustable freq, base frequency, modulation, duration, programmable color strobe, 4 wave forms, Freq Ramps, audio to visual pulse ratio adjust and programmable freq and color sets, plus 24 programmable freq. buttons. While being setup for use by laymen as well offering ease of use in the self programmed mode. Using tone generation for binaural brainwave synchronization, using the latest directX sound system oscillators, has 20 brainwave frequencies bands with a 2X and .5X function plus manual entry frequencies for a unlimited frequency spectrum for brain wave driving from delta to gamma, (1 to well over 400HZ). Adjustable base frequency (10HZ to 5000HZ), phase modulation 0% to 50% channel reversible, masking noise, Mixer controls, preset and programmable frequency controls. Also has a programmable color strobe (Stim / Background) stimulation section frequency driven with 4 independent different color pairs and sound to light ratio adjudtment with 1/2 of full screen usaage. A new just released upgraded version now has 24 programmable frequency buttons to store your favorite frequencies and comes pretuned to four of the major Schumann's resonance frequencies to enhance amplification of the naturally occurring peak frequencies of the brain. By using base frequencies that are an even 10X the frequency of the Schumann's resonance, further enhancement of driving efficiency is attained.(see Below) As of Ver 2.2 (this one is ver 4.0) all functions are now available from the pulldown menus as well, (Well over 110), added better durational display information, more percise timer controls, and better color choice information.
