What is Binaural Beat Generator?

The Binaural Beat Generator creates audio frequencies that can help with focus, relaxation, and sleep. This free tool generates two slightly different tones that your brain perceives as a single rhythmic beat — all audio is produced privately on your device.

Five wave-band presets are wired in: Delta (2 Hz, deep sleep), Theta (6 Hz, meditation), Alpha (10 Hz, relaxation), Beta (20 Hz, focus) and Gamma (35 Hz, peak awareness). The base tone ranges 100-500 Hz and the beat 1-40 Hz. You can render a session of 1, 5, 10 or 30 minutes to a WAV file and play it offline. A named session library also groups goal-based picks (Deep Work, Drift Off, Morning Boost) into Sleep, Relax, Focus and Energy tabs, the carrier shape switches between sine, triangle and square, and a live bar meter shows the sound is actually playing.

How to use

1. Set the base frequency and desired binaural beat frequency
2. Put on headphones for the best binaural effect
3. Press play and adjust volume to a comfortable level

When to use

• A 30-minute Alpha session in the background while writing or studying.
• A short Delta WAV to nap on during a long flight without internet.
• Trying Theta frequencies before a meditation session to see what helps you settle.

Result

Set a base of 200 Hz with a 10 Hz difference for an alpha-wave beat that promotes relaxation.

FAQ

Do binaural beats actually work?

The science is mixed. Small studies suggest mild effects on attention and relaxation, especially Alpha and Theta ranges, but results vary person to person. Treat it as a sound environment that may help focus or wind down, not a medical treatment.

Why do I need headphones for this?

For binaural beats, yes — the illusion only forms when each ear hears a slightly different frequency. Through speakers the two tones mix in the air and the brain perceives one combined sound instead of the beat. If you can't use headphones, switch to Isochronic mode: it pulses a single tone on and off and works fine on speakers.

What's the difference between Delta, Theta, Alpha, Beta and Gamma?

They mark different EEG frequency bands seen during sleep, meditation, calm wakefulness, focused thinking and high-attention tasks respectively. The presets pick the standard centre of each band so you can sample one without tuning manually.

Is it safe to listen at high volume for long periods?

Same rules as any audio. Long sessions at high volume can damage hearing. Keep the volume comfortable, take breaks, and avoid binaural beats while driving or operating machinery since some sessions can make you drowsy.

Why does the downloaded WAV file sound the same in both ears at first?

If you exported in Binaural mode, that's expected — the WAV holds two channels with two slightly different frequencies, and the beat only forms in stereo headphones. On a phone speaker or single earpiece it won't appear. Export in Isochronic mode instead and the pulsing is audible on any speaker.
