This is the prototype of an audio subliminal mixer patented (USP#1570381)
http://patft.uspto.gov/netacgi/nph-...170,381.WKU.&OS=PN/5,170,381&RS=PN/5,170,381 in the late eighties by Eldon Taylor, James Woodhams and myself (though I was never given credit).
"Audio subliminal recordings are made in which in addition to using a primary carrier, such as music, two audio channels are used to deliver subliminal messages to the brain. On one channel, accessing the left brain hemisphere, the message delivered is meaningfully spoken, forward-masked, permissive affirmations delivered in a round-robin manner by a male voice, a female voice and a child's voice. On the other channel, accessing the right brain, directive messages, in the same voices, are recorded in backward-masked (or meta-contrast). The three voices are recording in round-robin fashion with full echo reverberation. The audio tracks are mixed using a special processor which converts sound frequencies to electrical impulses and tracks the subliminal message to synchronize the subliminal message in stereo with the primary carrier. The processor maintains constant gain differential between the primary carrier and the subliminal verbiage and, with the subliminal verbiage being recorded with round-robin, full echo reverberation, ensures that none of a message is lost. The primary carrier should be continuous music without breaks or great differences in movements."
It should be obvious from the photos how the electrodes are applied, and the right and left brain signals are accessed and modulated.
