Binaural beat generator

Two pure sine tones, one per ear, generated live in your browser. The presets are designed around conventional EEG bands — what you experience is individual, and outcomes are not guaranteed.

Evidence: Emerging — Human studies show potentially useful relaxation effects in some contexts, but findings are mixed and protocol-dependent.

🎧 Headphones required A binaural beat is an auditory illusion created when each ear receives a slightly different frequency. Without stereo headphones, your ears hear both tones and the effect cannot form.

Choose a preset

Delta-range Designed around a 2 Hz beat — the range conventionally associated with deep sleep. Theta-range Designed around a 6 Hz beat — associated with drowsiness and meditative states. Alpha-range Designed around a 10 Hz beat — associated with relaxed wakefulness. Beta-range Designed around an 18 Hz beat — associated with active attention.

Before you listen

Use a comfortable volume; stop if anything feels uncomfortable.
Do not use while driving, cycling in traffic, or operating machinery.
This is an educational and recreational experience — not a treatment for any medical or mental-health condition.
