Binaural Beat & Frequency Generator

Play binaural beats or a specific frequency right in your browser — no account, no download, nothing stored. Pick a brainwave band or a preset like 432 Hz, set an optional timer, and press play.

200 Hz
Pure tone
Headphones required for binaural beats. The effect only works when each ear hears its own tone — through a speaker, the binaural beat disappears.
Keep the volume comfortable. If you have epilepsy or a seizure history, check with a doctor first. This is a wellness tool, not medical treatment — don't use it while driving.

How to use it

  • Binaural beat mode plays a slightly different tone in each ear; your brain perceives a pulse at the difference. Choose a brainwave band, or set the beat by hand. Use headphones.
  • Pure tone mode plays one steady frequency in both ears — handy for hearing 432 Hz, 528 Hz or a Solfeggio tone on its own. Works on speakers.
  • Give it time. Effects build with listening — 15–30 minutes is a fairer trial than a quick sample. The timer fades the sound out gently when it ends.
  • Judge by feel. Notice your focus, calm or sleepiness rather than chasing a dramatic sensation.

A quick, honest note on what to expect

Binaural beats have real but mixed evidence — helpful for some people with focus, relaxation and pre-sleep calm, but not a guaranteed switch for your brain. Specific frequencies like 528 Hz don't repair DNA or cure anything. We dig into all of this honestly in our guides on binaural beats, theta waves, 432 Hz and 528 Hz. Treat this tool as a pleasant, free way to explore — and enjoy it for what it is.
