White Noise Generator
Mask distractions with pure sound, synthesized live on your device — no audio files, no streaming, no uploads.
How it works
- Tap a preset or drag the sliders to mix your own soundscape.
- Press Play (sound starts only after you press — browsers require it).
- Optionally set a sleep timer so the sound fades out on its own.
FAQ
What's the difference between white, pink and brown noise?
White noise is bright and hissy; pink noise is softer and more balanced; brown noise is deep and rumbling, like a strong waterfall. Try them at the same volume and pick what your ears like.
Does it use data while playing?
No. Every sound is synthesized mathematically on your device in real time — nothing is downloaded or streamed, so it works fine offline after the page loads.
Will the sound keep playing if I lock my phone?
On desktop, yes. On mobile, background audio depends on your browser and OS — keeping this tab visible is the safest option.
Private by design: everything runs in your browser. Nothing is uploaded.
