About this tool

IconVault's Noise Generator plays white, pink and brown noise synthesized live with the Web Audio API, perfect for focus, study, masking office sounds and falling asleep. Pink noise is tuned to human hearing for comfortable all-day focus, while deep brown noise feels like rain or a waterfall at bedtime.

Shape the sound with low-pass and high-pass filters, set the auto-stop timer (10 minutes to 8 hours, including power nap and deep sleep presets), and let it fade out smoothly instead of cutting off. Everything is free and runs fully in your browser with no downloads or sign-up.
