Binaural Studio

Binaural beats happen when each ear hears a slightly different pure tone at the same time — for example 200 Hz in one ear and 210 Hz in the other. Your brain perceives a third, phantom beat equal to the difference between the two, in this case 10 Hz. The Binaural Studio generates both tones in real time and plays one to each ear, so you can set a carrier frequency and a beat frequency and hear the effect directly.

Yes. Binaural beats only form when each ear receives its own separate tone, which speakers can't reliably isolate because both ears hear a mix of both channels. Any stereo headphones or earbuds are enough — you don't need anything specialized.

It's completely free with no account, email, or payment required. The generator runs entirely in your browser using the Web Audio API, so there's nothing to install and nothing to unlock.

Start with what you're trying to do rather than the label. Delta (0.5–4 Hz) and Theta (4–8 Hz) suit sleep, deep rest, and meditation; Alpha (8–14 Hz) suits calm, relaxed focus; Beta (14–30 Hz) suits active concentration and everyday tasks; Gamma (30–100 Hz) suits short bursts of alertness. You can also skip the presets entirely and fine-tune your own carrier and beat frequency with the sliders.

No. Binaural Studio has no accounts, no server-side storage, and no tracking. Any preferences it remembers, such as your last-used settings, stay in your browser's local storage on your own device and are never transmitted.

The carrier frequency is the actual audible tone both ears hear, for example 200 Hz — a comfortable, neutral pitch. The beat frequency is the small difference between the left and right tones, which your brain perceives as a slow pulsing rhythm rather than a pitch. Changing the carrier changes how the tone sounds; changing the beat changes the entrainment rhythm.

The Alpha and Gamma sound pages are fixed, ready-to-play tracks tuned to one specific frequency for a quick, no-fuss session. Binaural Studio is the full generator behind them — it lets you choose any carrier and beat frequency, switch between all five brainwave presets, and fine-tune the mix yourself with live sliders and a visualizer.

There's no fixed rule, but the built-in session lengths (5, 10, 15, 30, and 60 minutes, or continuous) cover the common cases. Shorter sessions of 10–15 minutes work well for a quick focus reset, while 30–60 minute sessions suit meditation or winding down before sleep. You can stop at any time with the Start/Stop button.

You can, though each tool plays its own audio, so running Binaural Studio at the same time as another sound page will layer them. Many people instead use a Theta or Alpha preset here first to settle into a calm state, then move to the Breathe or Meditation pages, or use Focus Mode's own binaural preset directly within a timed session.

Binaural beats are generally considered safe for most listeners at a comfortable volume, but people with epilepsy or a history of seizures should be cautious with any rhythmic audio or visual stimulation and check with a doctor first. Keep the volume moderate, and stop if you notice discomfort, ringing in your ears, or a headache.
