A sleep sound machine in your browser
You don't need a bedside gadget to get sound-machine sleep. Mynded turns any phone, tablet, or laptop into a full sleep sound machine — white noise, rain, ocean, fan, thunder, and more, generated live with a fade-out timer. Press play to try the classic white-noise setting.

Everything a sound machine does — and more
A dedicated sound machine plays a handful of built-in loops at one bedside. Mynded synthesises each sound in real time, so nothing loops or repeats, and it travels with you — hotel rooms, the couch, a partner's place. Pick from eight sounds, adjust the volume, and let the sleep timer fade it out once you're under.
Why steady sound helps you sleep
Sound machines work by raising the room's background 'noise floor' so doors, traffic, and creaks stop standing out sharply enough to wake you. The steady texture also gives a racing mind something neutral to rest on — the same reasons white noise and rain are the most popular settings on any machine.
Mix your own soundscape
In the Mynded app you can layer sounds the way high-end machines do — rain over brown noise, ocean under a soft fan — then save the mix you like and set a 15-to-60-minute timer. It's the sound-machine experience without the machine.
Mix it, time it, sleep to it
In the Mynded app you can layer soundscapes, set a fade-out sleep timer, and add AI sleep stories and guided wind-downs — all shaped around how you feel tonight.

Is this really free — no machine to buy?
Yes. The sounds on these pages play free in your browser, generated in real time. A physical machine is just a speaker with loops built in; your phone or laptop already does the job.
Which sound machine setting is best for sleep?
White noise and rain are the most popular; brown noise suits people who find white noise hissy, and fan noise feels most familiar if you've always slept with a fan. Try a few nights of each.
Can I leave it running all night?
You can, at a moderate volume — or set the sleep timer so the sound fades out after you've drifted off and doesn't play until morning.
