Flat-spectrum noise for focus, sleep, and audio testing.
Export 5 seconds of white noise as WAV.
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.
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.
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.
