Noise generator

Play white, pink, or brown noise in the browser — for focus, sleep, or audio testing.

Noise type

Pink: softer, falls with frequency — often used for focus and sleep.

Sound is generated in this browser with WebAudio. Nothing is sent anywhere.

Start low — noise can be harsh on speakers and ears. Playback stops when the tab is closed; there is no sleep timer or offline file export.

How to use

  1. Pick a noise type.
  2. Set the volume low.
  3. Start, and stop when done.

What it supports

Loops a generated 2-second buffer — seamless but not endless randomness. No timer, no file export; closing the tab stops playback.
