White Noise Generator
Play white, pink or brown noise and blend in rain, ocean, wind and fire — to focus, relax, mask distractions or fall asleep. Mix your own soundscape, set a sleep timer, and let it run. Everything is generated in your browser; nothing loads or uploads.
Each sound is generated live with the Web Audio API — there are no audio files to download and it never repeats in an obvious loop. White noise is bright and even (great for masking voices); pink noise is softer and more natural; brown noise is deep and rumbly (a favourite for focus and sleep). Blend in rain, ocean, wind or a crackling fire to taste. Nothing is uploaded and there is no signup — leave it playing as long as you like.
White, pink and brown noise — what’s the difference?
- White noise — every frequency at equal energy: bright, even and hiss-like. Best for masking voices and sudden sounds.
- Pink noise — softer and more balanced, with less high-end. Sounds more natural, like steady rain; popular for sleep and study.
- Brown noise — deep and rumbly, with strong low frequencies. A favourite for focus, calming and blocking out low background noise.
How to use it
- Press Play (or tap a preset like Focus or Sleep to start instantly).
- Mix your sounds — raise the volume of any noise colour and blend in rain, ocean, wind or a crackling fire.
- Set the master volume to a comfortable, gentle level.
- Set a sleep timer (15–60 minutes) if you want it to stop on its own.
Presets
- Focus — brown noise with a hint of rain, to settle in and concentrate.

Frequently asked questions
Is brown noise better than white noise for focus and sleep?
Many people find brown noise’s deep, low rumble more relaxing and less harsh than white noise, which makes it popular for focus and sleep — but it’s personal. Try white, pink and brown here and use whichever feels best to you.
Can I mix several sounds together?
Yes. Each sound has its own volume, so you can blend, say, brown noise with light rain, or ocean waves with wind. The presets are good starting points.
Does it have a sleep timer?
Yes — choose 15, 30, 45 or 60 minutes and it fades out and stops on its own, so you can fall asleep to it.
Does it use up data or download files?
No. The sound is generated in your browser in real time, so after the page loads it uses no data and downloads nothing.
Does it upload anything?
No. There’s no recording and nothing to upload — it only plays sound your device generates.
Is it really free?
Completely — no signup, no watermark, no time limit.
