Free sleep sounds: rain, white noise & ASMR.

The sleep sounds are free. All 325 of them. 55 rain sounds, 37 white noise tracks including brown noise, pink noise, green noise and blue noise for sleep, 39 ASMR sounds, 96 ambient music tracks, and no ads between tracks, ever. Layer your own mix: rain on a tent over a crackling fire, ocean sounds under a slow train. Press play and the room changes.

What the trial adds: a voice under the sound. Rain alone can hold a room steady, but a racing head follows thoughts, not weather. The 7-day free trial opens the rest of the library: long bedtime stories for adults and guided sleep nights, told in a deep, unhurried voice you can lay under your rain or white noise mix. Save your mixes to your account, keep everything ad-free, and take it with you on iOS, Android and the web. Cancel anytime, in one tap, before you pay a penny.

The science behind sleep sounds. A steady sound gives the night a floor. Sudden noises stand out against silence (a door, a pipe, a passing car) and the brain startles toward them; rain, fans and white noise flatten those peaks so far less gets through. And a sound heard a thousand times before carries nothing worth waking for, which is why the oldest textures, rain on glass, waves, a settling fire, are the ones people sleep under. We've written it up in plain English: why rain sounds calm you, what pink noise does at night, and why ASMR works.

Whatever sound puts you under, it's here. Rain sounds for sleeping: drizzle, downpours, rain on glass, rain on canvas. Sleeping music and calming, relaxing sleep music. Ocean sounds for sleep, night sounds, thunderstorm sounds, fireplace and crackling fire sounds, fan noise for sleeping, train sounds for sleeping. Meditation music and soothing sounds for work and focus. Binaural beats for sleep. Sleep ASMR: taps, brushes, pages, whispers-without-words. Every colour of noise for sleep: white, brown, pink, green and blue. All free, all mixable, all without a single advert between tracks.

Prefer to be told a story? The bedtime stories for adults run an hour or more and fade out under you. Or let a guided night do the thinking. Both are included in the free trial.
