Summary
You are the active element
Headphones. A beat. An hour. Start free on the Console, or take Member for GUIDE, drums, infinite hold, and 250 extra programs.
A passive tool
A drug takes the lead until metabolism ends. A binaural difference tone does not. Two carriers, one in each ear, can produce a beat — Dove 1839, Oster 1973 — and then the rest of the hour is yours: breath, posture, whether you watch the inner field or check a phone.
Three shelves
Frequency keeps beat frequency and musical pitch on separate axes. Declassified is a reading room for Gateway-era audio notes and the remote-viewing paper trail — not a UAP magazine. Research is peer-reviewed work, newest first, mixed results included.
What to do
Stereo headphones. Comfortable volume. An aim you can say in one sentence, or a deliberate decision to have none. Treat the audio as support — not a medical device, not a drug substitute, not a psychic weapon.
Educational only. Not medical, military, or therapeutic advice. Headphones required for a true binaural beat.
