Binaural Beats Generator
Play two tones that create a beat frequency.
Two tones, one perceived beat
Binaural beats play a slightly different frequency in each ear, and the brain perceives a rhythmic beat at the difference between them. Enthusiasts use them for focus, relaxation, and meditation.
Set a base frequency and the beat frequency you want, put on headphones, and press play. The left and right tones combine into the beat only when each ear hears its own channel.
Experimental and private
The tones are generated in your browser, so nothing is uploaded.
