White Noise Generator

Choose a noise type — white, pink, or brown — and press play. The sound is synthesized in real time with the Web Audio API, so there are no files to download and no loop seams, and it can run for hours. White noise spreads energy evenly across frequencies, pink noise leans warmer like steady rain, and brown noise is deeper, like wind or a waterfall. Combine the volume slider with the sleep timer (15/30/60/90 minutes) for focus sessions or falling asleep.
