How to use it
Three steps, no learning curve.
- 01
Set the picture
Choose the static intensity and refresh speed. Scanlines and a vignette make it read as a CRT rather than random pixels.
- 02
Add sound if you want it
The audio is generated live in your browser — white, pink or brown noise — so there is no file to download and no streaming.
- 03
Fullscreen it
Static works as a sleep aid, a focus mask for a noisy office, or a convincing dead-channel effect for film and streams.
Three colours of noise
Pick the one that matches the sound in your head.
Pink noise
Energy falls as frequency rises. Softer and more natural — often described as steady rain or a fan.
Brown noise
Much more low-frequency energy. A deep rumble that many people find easiest to sleep through.
FAQ
Common questions
Why do white, pink and brown noise sound different?
They differ in how much energy sits at each frequency. White noise is flat across the spectrum and sounds hissy; pink noise rolls off the treble and sounds more like rain; brown noise rolls off further still and sounds like a low rumble.
Is the audio streamed from a server?
No. The noise is generated in your browser with the Web Audio API at the moment you press play. Nothing is downloaded and nothing is uploaded.
Can I leave it running all night?
Yes. Turn on keep-awake if the screen matters to you, and consider lowering the volume and using black screen instead if you only want the sound — audio usually keeps playing while the screen is off.
Does static help you sleep?
Many people find steady broadband noise masks unpredictable sounds and makes it easier to fall asleep. It is not a medical treatment, and if you have tinnitus or hearing concerns, keep the volume low.
