A free online noise machine that generates white, pink and brown noise entirely in your browser. Pick a noise color and press Play. White noise is a bright, even hiss that's great for masking chatter and keyboard clatter. Pink noise is balanced and softer, like steady rain — handy for focus and studying. Brown noise has a deep, rumbly low end like a waterfall, which many people find calming for sleep or for soothing a baby. You can adjust the volume and the tone (a low-pass filter): lower the tone for a rounder, gentler sound. Set a sleep timer from 15 to 90 minutes and the sound fades out and stops on its own, so it won't run all night. Because the sound is generated on your device with the Web Audio API, there's no audio file to download and no ads like a video site. Your noise color, volume, tone and timer are saved in your browser, ready next time. Everything happens on your device — nothing is recorded, uploaded or sent to a server. No install, no sign-up, free, and it works on desktop and phone.
How to use
- Choose a noise color: white, pink or brown.
- Adjust the volume and tone (low-pass) to taste.
- Press Play. For sleep, set a timer so it stops on its own.
