What is a white noise generator?
A white noise generator creates a steady broadband sound that can mask speech, traffic, and sudden background noises. This browser tool also makes softer pink noise and deeper brown noise, with volume, brightness, and timer controls. The sound is synthesized on your device instead of streamed from a recording.

FAQ
Is the white noise generator free?
Yes. You can play white, pink, and brown noise, use the timer, and download short WAV files without an account or payment. There is no daily session limit, although playback stops when you close the page or your browser suspends the tab.
Is any audio recorded or uploaded?
No. The generator does not request microphone access, record your room, or upload a listening session. It synthesizes random samples with the Web Audio API on your device. Downloaded WAV files are also assembled locally inside the browser.
How long can the noise play?
Playback continues while the page remains open and active. You can leave the timer off or choose a 15, 30, or 60 minute stop. Browsers and mobile operating systems may pause audio when a tab is hidden, a device locks, or power-saving rules take over.
What is the difference between white, pink, and brown noise?
White noise spreads energy evenly per frequency and sounds bright. Pink noise reduces energy as frequency rises, giving a smoother balance per octave. Brown noise reduces high-frequency energy more steeply, producing the deepest and softest-sounding profile of the three.
Which noise color is best for sleep or focus?
There is no universal best color. White noise can mask sharper sounds, while many listeners find pink or brown noise gentler for long sessions. Try each at the lowest volume that covers the distraction. Personal comfort matters more than choosing a specific label.
Can I use this for tinnitus?
Broadband sound may help some people mask tinnitus temporarily, but this generator is not a diagnosis or treatment. Keep headphone and speaker levels comfortable. If tinnitus is persistent, one-sided, sudden, or distressing, seek advice from a qualified hearing professional.
Does it work offline?
Once this page and its code are loaded, the sound generation itself does not need a server connection. A browser may still require the page to remain open, and a fresh visit needs a connection unless the site is already cached on your device.
