What's the difference between white, pink and brown noise?

White noise has equal energy across all frequencies (a harsher, more "hissy" sound); pink noise reduces higher frequencies for a softer, more balanced sound; brown noise reduces them further still, for a deep, rumbling tone many find more soothing.

Can I download the noise instead of just streaming it?

Yes, you can download a file to play offline or loop in another app, not just play it directly on the page.

How long does the generated audio play for?

It's designed to loop continuously for as long as you need — for sleep or long focus sessions, it isn't limited to a short clip.

Does White Noise Generator upload my files to a server?

No. White Noise Generator runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Steady background sound — white, pink or brown noise — is widely used to mask distracting noises, help with focus, or ease into sleep, but finding a version that plays reliably (not a looping YouTube video with ads) and lets you choose the exact noise color isn't always straightforward. This tool plays or generates downloadable white, pink or brown noise on demand, letting you pick the noise character that works best for masking sound, focus or sleep.
