Question 1

What is Binauro and is it free?

Accepted Answer

Binauro is a free, open audio generator website running entirely in your browser. You can create custom binaural beats, isochronic tones, and ambient soundscapes for focus, sleep, and meditation without any cost, ads, or login.

Question 2

Do I need headphones for Binaural Beats?

Accepted Answer

Yes. Binaural beats work by playing two slightly different frequencies in each ear (e.g., 200Hz and 210Hz) to create a perceived 'beat' (10Hz) inside the brain. For Isochronic Tones or Ambient Noises (Rain, Brown Noise), you can use speakers.

Question 3

Can I use Binauro offline?

Accepted Answer

Yes! Binauro is a Progressive Web App (PWA). Once loaded, all audio generation happens locally on your device via the Web Audio API. You can install the app on your phone and use it without an internet connection.

Question 4

Which frequency should I choose for sleep or focus?

Accepted Answer

For deep sleep, use Delta waves (0.5–4 Hz). For meditation and relaxation, try Theta (4–8 Hz). For relaxed focus, Alpha (8–14 Hz) is best, while Beta (14–30 Hz) is ideal for high-energy concentration and problem-solving.

Question 5

What is the difference between Isochronic Tones and Binaural Beats?

Accepted Answer

Binaural beats require headphones and create a continuous illusion of a pulse. Isochronic tones use a single tone that turns on and off rapidly. Isochronic tones are often perceived as more distinct and work effectively over loudspeakers.

Question 6

Is my usage private?

Accepted Answer

100%. Since the audio engine runs in your browser (client-side), no audio data is ever sent to a server. Your custom presets and settings are stored on your device.
