White Noise Generator
Play white, pink or brown noise for sleep, focus or masking background sound. Shape the tone, add a slow ocean-like swell, set a sleep timer that fades out, and download minutes of noise as a WAV. No app to install and no account to create.
Generate noise
Start at a low volume, especially with headphones. Space bar plays and stops.
Presets
Presets are shaped noise, not recordings. Fan is pink noise softened to 1.5 kHz, Ocean swell is brown noise with the swell on, Deep rumble is brown noise cut at 400 Hz.
Sleep timer, save or share
The timer fades the noise out over its last 30 seconds. The WAV is 16-bit stereo at 44.1 kHz with the current color, tone, swell and volume, about 10 MB per minute. Where the browser allows it, playback continues with the screen off and the lock screen shows a pause button.
