Sleep Sounds
An ASMR library and gentle noise machine — every sound generated live in your browser. Endless, seamless, free.
ASMR library the good stuff
Close-up, tingly textures. Layer two or three for your own scene.
Nature & noise
The classics — masks, soothes, never loops.
Sleep timer
Why generated sound?
Every soundscape here is synthesized in real time — endless, seamless, never looping. The ASMR textures sit close to the ear; the noise beds mask hallway chatter and traffic. Pick one, or build a scene: fire + crickets, heartbeat + brown noise, stream + chimes.
The timer fades everything out gently over the last minute, so nothing wakes you back up.
