About this tool
This white noise generator synthesizes white, pink and brown noise plus rain sounds in real time, right in your browser. These even, continuous sounds have no jarring peaks, so they mask nearby talking, keyboards and traffic and help many people focus, relax or fall asleep more easily.
The sound is generated live with Web Audio rather than playing a fixed file, so there is no looping seam and nothing to download. You can adjust the volume any time, and all processing happens locally.
How to use
- Click one of white, pink, brown noise or rain to start playing.
- Use the volume slider to set a comfortable level.
- To change the tone, simply click a different card.
- Click the currently playing card again to stop.
When to use it
- Mask noise in a busy environment to focus while working or studying.
- Provide a steady background sound for falling asleep or soothing a baby.
- Create a calm sound backdrop for meditation or relaxation.
- Ease tinnitus or sensitivity to sudden sounds.
FAQ
What is the difference between white, pink and brown noise?
They differ in energy distribution: white noise is even across frequencies and sounds "brighter"; pink noise has more low end and is softer, closer to nature; brown noise is the deepest, like a low waterfall or surf. Try each and pick what feels best.
Does it download audio or use data?
No. The sound is synthesized live in your browser; no audio file is downloaded and it does not keep using data.
Can it play continuously for a long time?
Yes, as long as the page stays open and in the foreground. Keep the volume moderate and protect your hearing during long sessions.
