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. No repeats. Like a dedicated premium 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 limits.

20 SOUNDS. ALL GENERATED. NONE RECORDED.
Five noise colors, seven fan variants, and eight mechanical sounds. Every one synthesized on your device in real time.

NOISE COLORS
White noise, pink noise, and brown noise, each synthesized and filtered to precise frequency specifications. Green noise, mid-focused with the bass rolled away, so it masks without the weight of pink or brown. Grey noise, tuned to how your ears actually hear, so it sits evenly across the spectrum instead of pushing at one end. Not recordings. Not samples. Pure, continuous sound generated on your device.

FAN SOUNDS
Seven variants: slow, medium, fast, box, ceiling, bladeless, and tower fan. The most popular sound category on dedicated hardware noise machines, synthesized with zero room noise or recording artifacts. Slow Fan is free. Six more with Premium.

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

TUNE EVERY SOUND
Long-press any sound to open its tuning controls. 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. Not a coarse slider.

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, 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.
