Binaural beats generator
Generate binaural beats in your browser by setting a beat frequency and a carrier tone. Stereo headphones are required.
Preset names refer to commonly used brainwave frequency bands. They do not guarantee a particular mental or emotional effect.
How to use
- Put on stereo headphones or earbuds. With ordinary speakers, both ears usually receive both tones, so the intended binaural effect may not be preserved.
- Pick a preset, or set the beat frequency yourself. That value is the difference between the two tones, and it is the pulse you hear.
- Set the carrier tone. This is the pitch the beat rides on. Lower carriers sound deeper, higher carriers sound brighter.
- Start the volume low, then press Play binaural beat.
- Adjust any control while playing. The tone is regenerated with the new settings, so the sound restarts from the beginning.
How it works
With the carrier tone set to 200 Hz and the beat frequency set to 10 Hz, your left ear receives a 200 Hz tone and your right ear receives a 210 Hz tone. The difference between the two tones is 10 Hz.
Lower beat frequencies may be perceived as slow pulsing. Higher beat frequencies, such as 40 Hz, may sound more like rapid vibration, roughness, or buzzing.
Some people listen to binaural beats while focusing, relaxing, meditating, or preparing for sleep. Scientific evidence for specific benefits remains mixed, and responses vary between listeners.
This generator is intended for personal listening and experimentation. It is not a medical treatment or diagnostic tool. Start at a low, comfortable volume and stop if the sound causes discomfort.
