The Gateway

The Gateway generates precision binaural beats in real time using on-device sine wave synthesis. Nothing is pre-recorded or streamed. Every session is built on the focus level system described in two declassified U.S. government documents from the CIA FOIA Reading Room: the 1983 U.S. Army "Analysis and Assessment of Gateway Process" and the 1977 Gateway Experience Intermediate Workbook.

WHAT'S INSIDE

• Focus 10 and Focus 12 binaural sessions with no time limits
• A real-time audio engine with per-stage frequency transitions and smooth fades
• Procedurally generated ambient sounds: brown, pink, and white noise, rain, ocean, wind, cave, singing bowls, and a 432 Hz drone
• Seven Daily Tools — short guided practices that work without headphones
• Session history with progress tracking
• A Learn section on auditory entrainment and the Focus Level system
• Background playback with lockscreen controls

HOW IT WORKS

A binaural beat is created when each ear hears a slightly different frequency. Your brain perceives the difference as a slow rhythmic pulse and tends to follow it — a phenomenon called auditory entrainment. Sessions move through timed stages targeting delta, theta, alpha, beta, or gamma ranges. Stereo headphones are recommended for binaural sessions; Daily Tools need none.
