Veil: White Noise Sleep Sounds

Veil is the white noise machine your phone should have been all along.

Every sound is generated in real time. No audio files. No loops. Ever. Like a dedicated hardware noise machine, Veil produces truly infinite sleep sounds that never click, pop, or restart.

White, pink, and brown noise plus a fan sound are completely free. No time limits. No subscription.

14 SOUNDS. ALL GENERATED. NONE RECORDED. Three noise colors, five fan variants, and six mechanical sounds. Every one synthesized on your device in real time.

NOISE COLORS White, pink, and brown noise, each filtered to precise frequency specifications. Not recordings. Not samples. Pure continuous sound generated on your device.

FAN SOUNDS Five variants: slow, medium, fast, box, and ceiling. The most-used sound category on dedicated hardware noise machines, synthesized with zero room noise or recording artifacts. Slow Fan is free. Four more with Premium.

MECHANICAL SOUNDS Window AC, central AC, airplane cabin, clothes dryer, vacuum, and shower. Deep, familiar sounds that mask everything from traffic to snoring.

TUNE EVERY SOUND Adjust cutoff frequencies, oscillation speed, tone, depth, and more. Shape white noise from bright and crisp to dark and muffled. Slow a fan down or speed it up. Make brown noise rattle-deep or smooth. Every parameter updates in real time while the sound plays.

PRECISION VOLUME A fine-grained analog-style volume control that lets you dial in the minimum effective masking volume.

MIX UP TO 3 SOUNDS Layer noise colors with fan sounds or mechanical hums. Independent volume per channel. Save your favorite mixes and recall them instantly.

SLEEP TIMER Presets or custom duration. Audio fades out gently so you never wake to sudden silence.

PLAYS ALL NIGHT Works with the screen locked and in the background until you stop it. Lock screen controls included.

WORKS OFFLINE Every sound is generated on your device. No internet required. No streaming, no downloads, no sound packs. Works on airplanes, in hotels, anywhere.
