How to use the binaural beats generator
- Put on headphones — the effect only works when each ear hears its own tone.
- Pick a brainwave band: delta for sleep, theta for meditation, alpha to relax, beta to focus or gamma.
- Fine-tune the carrier and beat frequency sliders, and blend in a little pink noise if you like.
- Press Play, set a sleep timer if you want, or export a 1, 5 or 10-minute session to listen offline.
This binaural beats generator plays two pure sine tones, one in each ear, with a small frequency gap between them. Your brain perceives that gap as a slow pulse — the binaural beat — which people use as a backdrop for focus, meditation, relaxation and sleep. The presets cover the classic delta, theta, alpha, beta and gamma ranges, and the live readout shows the exact left and right frequencies so you always know what you are hearing. Add a touch of pink noise to soften the tone, use the sleep timer to fade out at night, or export a session to loop on your phone. Everything runs locally with no upload and no signup.
FAQ
Do binaural beats really need headphones?
Yes, headphones are essential. A binaural beat works because each ear hears a slightly different tone and your brain perceives the difference between them. On speakers the two tones mix in the air before they reach your ears, so the effect disappears. Any stereo headphones or earbuds will do.
Which brainwave band should I choose?
It depends on your goal. Delta around 2 Hz is associated with deep sleep, theta around 6 Hz with meditation, alpha around 10 Hz with calm relaxation, beta around 20 Hz with focused work, and gamma around 40 Hz with alertness. Try a preset, then fine-tune the beat and carrier sliders until it feels comfortable.
Can I download a binaural beats session to play offline?
Yes. Choose a length of 1, 5 or 10 minutes and export the session to MP3 or WAV. The file is rendered with your exact carrier, beat and noise settings and includes gentle fades, so you can loop it on a phone or music player without needing a connection.
Are binaural beats safe and do they actually work?
For most people binaural beats are a safe, pleasant background sound, but they are a relaxation aid, not a medical treatment, and individual results vary. Avoid them while driving, and if you have epilepsy, a pacemaker or any health concern, check with a doctor first. Treat them as one tool among many for winding down or focusing.
