White, pink and brown noise with an optional soft 432 Hz tone, generated live in your browser. Play, relax, and set a timer.
A simple player for calm background sound. Choose brown, pink or white noise, add an optional soft tone tuned to 432 Hz, set your volume and a sleep timer, then press play. Everything is generated live in your browser, so there are no files to download and nothing is uploaded.
White noise is bright and full, with every frequency at equal strength. Pink noise is softer and more balanced, a little like steady rain. Brown noise is deeper still, closer to a low rumble many people find soothing for focus or sleep.
The coloured noises are broadband, so they have no single pitch. 432 Hz is a tuning, the idea of setting the note A to 432 rather than the usual 440. Here it is a gentle sine tone you can layer under the noise if you like the sound of it. It is offered as a pleasant option, with no claims made about health or brainwaves.
Yes, and it runs entirely in your browser.
That's the whole list. A short note when there's something new worth your time. Leave whenever you like.
