🎧 Headphones required — binaural beats only work when each ear hears a different frequency.
How it works
- Put on headphones.
- Choose a base tone and a beat frequency.
- Click "Play" — one ear hears the base tone, the other hears the base tone plus the beat frequency.
FAQ
Why do I need headphones?
A binaural beat is an illusion your brain creates when each ear hears a slightly different tone — through speakers, both tones mix together in the air before reaching either ear, so the effect is lost.
Is there scientific evidence binaural beats help focus or sleep?
Research is mixed and effects are modest at best — treat this as a background-sound tool to try, not a guaranteed remedy.
What is the base tone vs. beat frequency?
The base tone is the pitch played in one ear; the other ear hears the base tone plus the beat frequency. Your brain perceives the difference between them as a subtle pulsing "beat".
Is any audio uploaded or recorded?
No — both tones are generated live by the Web Audio API in your browser.
