Two tones · one calm
Sound that tunes the mind.
Binaural Waves plays a slightly different tone in each ear. Your brain hears the difference as a slow, steady beat — and settles into sleep, focus, or stillness.
What's inside
An instrument, not a playlist.
Every sound is built around a precise frequency. Shape it, time it, and let it run in the background.
The physics
Different frequencies, different states.
The gap between the two tones — measured in hertz — is what the brain follows.
| Band | Beat | State |
|---|---|---|
| Delta | 0.5–4 Hz | Deep, dreamless sleep |
| Theta | 4–8 Hz | Meditation, drifting off |
| Alpha | 8–13 Hz | Calm, relaxed alertness |
| Beta | 13–30 Hz | Focus and steady attention |
| Gamma | 30–60 Hz | Peak concentration |
Headphones or earbuds are required for the binaural effect — each ear needs its own tone.
