Open White Noise & Ambient Sound Generator when you want background sound for sleep, focus, or blocking out distracting noise, without installing an app.

When it fits

White Noise & Ambient Sound Generator fits right in while studying or working, while trying to fall asleep, or any time a steady background sound helps you tune out a noisy room. Pick white noise for a flat hiss, pink or brown noise for something deeper and less harsh, or the ocean-waves mode for a slow swelling rhythm layered over brown noise. The sleep timer (15 to 120 minutes) lets you start it and stop worrying about turning it off.

When to skip it

Skip it if you need real recorded nature audio - every sound here, including "Ocean waves", is synthesized by the browser, not a sampled recording. It also will not keep playing once you close the tab, and most mobile browsers pause or throttle it once the screen locks.

Browser tool, white noise app, or looping ambient video

Three common ways to get background sound are White Noise & Ambient Sound Generator in the browser, a phone or desktop white noise app, and a long looping ambient video on a streaming site. An app has to be installed before it plays, although its audio does stay on your device; a looping video needs no install but is streamed from a server, usually offers a single fixed track, and rarely includes a sleep timer. Because White Noise & Ambient Sound Generator builds every sample in the browser itself, nothing buffers or depends on a network connection once the page has loaded, and it works on any device with a browser.
