◯ The Tone Generator

A native soundscape & binaural beat console for sleep, focus, and lucid dreaming

Built from the ground up for Android — not a wrapped website. Twelve hand-built sound engines synthesized in real time (not looped samples), a three-layer Binaural Core, isochronic tones, and a session sequencer built on the Hemi-Sync approach described in Robert Monroe's work and the declassified Gateway Process report. Runs on Android's native audio engine for real background playback — no browser tab to keep alive, no ads.

What's inside

Binaural Core

Three independently tunable brainwave layers — Delta, Theta, Alpha — each with its own carrier and beat frequency, a live waveform monitor, and five carrier-tuning presets from gentle octave spacing to a fully custom "God Mode." Layer them together for a program that shifts with you through the night.

Isochronic Tones

A pulsing single-tone entrainment layer with fully live-tunable carrier and beat frequency. No headphones required — unlike binaural beats, isochronic tones work through speakers too.

12 real-time sound engines

Ocean, Rain, Rain on a Tin Roof, Thunder, Wind, Fire, Crickets, Brook, Resonant Tuning, Drift, Pink Noise, Brown Noise — each synthesized live, not a looped sample.

Session Sequencer

Build a timed program that eases you down through the layers and back up, step by step — a real wind-down-to-wake arc instead of one static tone all night.

Sleep Timer

Quick-set 15/30/45/60-minute countdown that fades your session out smoothly instead of running all night.

Wake Alarm + Dream Log

Set a wake time and the app fades you up through alpha with an alerting tone, even with your phone locked. Hit Sleep Now to ease back down — it also grabs a 30-second voice note so you can capture a dream before it fades.

XY Oscilloscope

A live Lissajous vectorscope with color-coded, phosphor-trailed traces for six engines at once. Watch your session's actual waveform geometry shift in real time.

Presets & save slots

9 built-in presets plus 6 slots to save your own — long-press any sound to grab exactly what's playing.

Binaural beats and brainwave entrainment audio are used for meditation, focus, and sleep support. They are not a medical treatment, and the effect varies by listener. Headphones are required for binaural beats (isochronic tones work through speakers). If you have epilepsy or a serious health condition, check with a doctor before use.
