About This Tool
This online White Noise Generator is your ideal companion for work, study, and rest. It uses the browser Web Audio API to synthesize high-quality audio streams in real-time, without downloading any files. The tool offers three classic noise types: "White Noise" with equal energy to block distractions; "Pink Noise" which is softer and natural for relaxation; and "Brown Noise" which is deep and rumbling for deep sleep. You can also set a sleep timer (15/30/60 mins) to turn off the sound automatically.
