White Noise
Audio is synthesized live in your browser — nothing is downloaded. Press play to start.
White noise is an equal mix of every frequency, which gives it that steady, full “hiss” like an untuned radio, a box fan, or air rushing from a vent. It is the brightest and most even of the noise colors, so it does the most to cover up sudden or high-pitched sounds around you.
Because white noise is bright, some people find it a little harsh for long stretches. If it feels too sharp, tap Pink or Brown above — those roll off the treble for a softer, deeper sound.
The noise colors
- White — Flat, full hiss.
- Pink — Balanced, softer.
- Brown — Deep low rumble.
- Blue — Bright, airy hiss.
- Green — Mid-focused.
Every color here is generated from scratch with the Web Audio API the moment you press play — there are no sound files to load and nothing leaves your device. That is also why it keeps working offline once the page has loaded.
