Three studio-grade audio tools for focus, sleep, and meditation — monaural beats and isochronic tones that work on any speaker, plus binaural beats for headphone sessions. Presets, noise overlay, and session tracking included.
Or try the calm version — pick a state, press play.The beat is mixed directly into the audio signal — works on any speaker or headphone, no stereo channel separation required.
Slightly different frequencies sent to each ear — your brain perceives the difference as a beat. Requires stereo headphones for the effect to work.
A single tone pulsed sharply on and off at the entrainment rate. Strong evoked response without headphones — many find these the most direct of the three.
Adjust base frequency (80–600 Hz), beat frequency (0.5–50 Hz), carrier waveform, and volume. Fine-tune to exactly what works for you.
Quick presets for Delta, Theta, Alpha, Beta, and Gamma ranges with real-time band identification and descriptions.
Real-time waveform display powered by the Web Audio API analyser node. See the interference pattern as it plays.
Unlike binaural beats, monaural beats mix externally. The amplitude modulation is in the signal itself — any speaker works.
Set timed sessions from 5 to 60 minutes. Audio fades out automatically when your session ends.

Binaural beats are an auditory illusion: two slightly different frequencies are played, one into each ear, and the brain perceives the difference as a rhythmic beat at the entrainment frequency. They require stereo headphones to work.
Binaural beats require headphones — each ear hears a different tone. Monaural beats are two tones mixed into a single signal, so the beat is audible on any speaker. Isochronic tones are a single tone pulsed sharply on and off at the entrainment rate, producing the strongest evoked brain response without headphones.
Only the binaural studio requires stereo headphones. The monaural and isochronic studios work on any speaker — phone, laptop, or hi-fi.
Yes — the web version is free, with no account, no ads, and no tracking. Donations are optional and support ongoing development.
Delta (0.5–4 Hz) for deep sleep and recovery. Theta (4–8 Hz) for meditation and creativity. Alpha (8–13 Hz) for relaxation and calm focus. Beta (13–30 Hz) for concentration and analytical work. Gamma (30–50 Hz) for peak cognition, learning, and memory consolidation.
Research suggests effects on attention, mood, and learning consolidation. A 2020 study by Ross & Lopez published in Scientific Reports found 40 Hz binaural beats produced measurable gamma entrainment in MEG recordings and accelerated training benefits via overnight memory consolidation. Effects vary by individual — start with short sessions and see what works for you.
Yes. Brain Beats is a Progressive Web App (PWA). On mobile and desktop browsers you can install it to your home screen or app launcher, and it works offline after the first visit. No app store required.
For most people, brainwave entrainment audio is well-tolerated. However, if you have epilepsy, a seizure disorder, are pregnant, have a pacemaker, or are prone to severe migraines, consult a healthcare professional before use. Don't listen while driving or operating machinery.
Brain Beats is free in your browser — supported by listeners like you.
