Binaural Beat Generator
Binaural Beat Generator
Set a base tone and a beat frequency and the tool sends a slightly different pitch to each ear. See which brainwave band the beat falls in. Headphones required.
How binaural beats work
When each ear hears a slightly different frequency, the brain perceives a third, slow pulsing tone at the difference. For example 200 Hz in the left ear and 210 Hz in the right produce a 10 Hz beat. People use these for focus, relaxation or sleep playlists.
How to use it
Put on headphones, set the base and beat frequency, and press Play. Download a 30-second stereo WAV to build longer tracks.
FAQ
Do I need headphones?
Yes. The effect relies on each ear receiving a different tone, which only happens cleanly with headphones.
What do the bands mean?
Delta, theta, alpha, beta and gamma are ranges of brainwave frequency that people associate with sleep, relaxation, calm focus and alertness.
Are binaural beats proven?
Experiences vary and the science is mixed. Treat them as a relaxation or focus aid, not a medical treatment.
Is it free?
Yes, free forever.
