Generate white, pink or brown noise for focus, sleep or sound masking, with an optional timer. Runs in your browser, nothing is recorded.
White noise is equal energy per frequency; pink and brown noise have progressively more low-end and sound softer or deeper. Generated live in your browser with the Web Audio API. Nothing is recorded or uploaded.
White noise has equal power across all frequencies and sounds bright, like static. Pink noise rolls off the highs so it sounds more balanced and natural (like steady rain). Brown noise has even more bass and sounds deep, like a waterfall or distant surf.
Many people use it to focus, fall asleep, mask tinnitus, or cover distracting background sounds in an office or shared space. Pink and brown are popular for sleep; white is common for masking.
No. The noise is generated live in your browser with the Web Audio API, so there is no download, no file and nothing is uploaded. The optional timer stops it automatically.
