Stereo sine-tone binaural beat generator with brainwave presets and sleep timer.
Headphones required. Binaural beats rely on a different frequency in each ear — they do not work through speakers.
Disclaimer: Binaural beats are intended for relaxation and focus experimentation only — they are not a medical treatment. Keep the volume low, especially for long sessions, and stop if you feel discomfort.
Generate binaural beats with two precisely tuned sine tones panned hard left and right. Choose a carrier frequency (100–500 Hz) and a beat frequency (0.5–40 Hz), or tap a brainwave preset — Delta for deep sleep, Theta for meditation, Alpha for relaxation, Beta for focus, Gamma for concentration. Includes a volume control and an auto-stop timer. Headphones required for the effect. Runs entirely in your browser.
