What's the difference between the noise types?

White noise mixes every frequency evenly and sounds the crispest, pink noise emphasizes lower frequencies for a softer sound, and brown noise emphasizes the low end even further, sounding like deep waves or a waterfall.

Does this download a real recorded nature sound?

No. This tool doesn't use any audio files at all — the sound waveform is computed in real time in your browser using the Web Audio API, so there are no copyright concerns and no file size to worry about.

How does the auto-stop timer work?

Choose an auto-stop time before you press Play, and playback stops automatically once that much time has passed. Leave it set to "Off" and it keeps playing until you press Stop yourself.

White Noise Player - White, Pink & Brown Noise

What is a white noise player?

The White Noise player generates white, pink, and brown noise directly in your browser using the Web Audio API. Instead of downloading a recorded nature-sound file, it computes the sound waveform in code on the spot, so there are no copyright concerns and playback never stutters even on a slow connection. White noise mixes every frequency evenly, pink noise emphasizes the lower frequencies for a softer sound, and brown noise emphasizes the low end even further for a deep, wave-like rumble.

How to use it

Pick the noise type you want and press "Play" to start hearing it right away. You can adjust the volume with the slider while it's playing, and if you set an auto-stop time in advance, playback stops on its own once that time has passed. To switch noise types, press "Stop" first, then pick a new one.

When it comes in handy

Masking background noise to stay focused while studying or working
Playing a soothing background sound before falling asleep (use the auto-stop timer so it doesn't run all night)
Blocking out office or café noise
Providing a steady background sound while putting a baby to sleep or meditating
