What white noise is

White noise has equal intensity across the audible spectrum — like static on an untuned TV. It masks sudden environmental sounds, which is why people use it for sleep, study, and office focus.

How to use this generator

Press Play and set volume low enough to blend with your room, not overpower it. For sleep, start quieter than you think you need. Export WAV to use the same noise offline on a phone or sleep speaker.

When to try other colors

If white noise feels harsh, try our Pink Noise (warmer) or Brown Noise (deeper bass). Each color has different spectral weighting but the same privacy guarantee — everything runs locally.
