What is this?
Free the Noise generates background sound right in your browser. Nothing is recorded or downloaded: the noise is calculated as it plays, so it never repeats. It masks distracting sounds and helps with focus, sleep, meditation and tinnitus.
Which sound?
- Brown: deep, heavy rumble, like a waterfall. Good for sleep.
- Pink: balanced, like steady rain. A good all-rounder.
- Green: centred on the middle frequencies, like a natural ambience.
- White: even static across all frequencies. Masks the most.
- Blue: crisp, brighter hiss.
- Violet: the brightest, high-pitched hiss.
All six play at the same loudness, so switching never makes you jump.

Playing with the screen off
On Android the sound keeps playing in the background, with controls in the notification (it plays a seamless 32-second loop there). iPhones may pause the sound when the screen locks or you switch apps: for uninterrupted sound there, keep the page open in front; it keeps the screen awake while playing.
