A storm built as you listen instead of streamed from a file. Pick what it is falling on and how hard, and leave it running. Thunder turns up on its own schedule.
Real field recordings, public domain, crossfaded so you never hear the loop come round. Thunder is separate and arrives on its own schedule, so no two nights sound the same.
This page used to synthesise every drop in your browser, and on paper it worked: measured against real recordings it landed within a few hundred hertz on brightness. What it could not fake was texture. Rain on a window carries roughly one clear impact a second; the synthesised version carried seven, and that difference is the whole difference between rain and static.
So it is real weather now, recorded outdoors by people who left a microphone out in it and released the results into the public domain. What we still do ourselves is the joinery: two copies of each recording run apart and crossfade into one another, so the loop never announces itself, and the thunder is kept separate and fired on its own schedule rather than baked in.
Short answers, including to the ones we would rather dodge.
Yes, and it did not start that way. The first version of this page synthesised every drop in the browser. It measured close to real rain on brightness, but it carried around seven prominent droplet impacts a second where actual recordings of rain on a window carry closer to one. Real rain through glass is smoother than you would guess, and that texture was not something tuning was going to invent.
So these are real field recordings, all of them released into the public domain under CC0, which means no attribution is owed and nothing is licensed from anyone.
Technically yes, but you should not be able to hear it. Two copies of the same recording run slightly apart and hand over to each other with a three second crossfade, so the seam never lands in the open. Thunder is stored separately and fired on its own schedule rather than baked into the loop, which is what stops a night sounding like the same minute over and over.
Each one is a different recording rather than the same audio through a filter. Rain on glass, rain on a tin roof, rain on a tent and rain in woodland genuinely do not sound alike, and no amount of EQ turns one into another.
Yes, and the setting is remembered. Left on, it fires every fifteen to fifty seconds and picks between a distant peal, a rolling one and a proper clap depending on how close that particular strike is meant to be, with the flash on the glass matching it.
No. Not doctors, not sleep scientists, not therapists, not qualified in any of this. We are people who could not sleep, got interested in why, and started building small things to try on ourselves.
So read everything here as somebody's experiment rather than as advice. Where we mention research we have tried to describe it honestly, including the parts where the evidence is thin, but we are reading it as curious amateurs and you should treat it that way too.
If you genuinely cannot sleep, night after night, for weeks, that is worth taking to someone qualified. Insomnia is treatable and the treatment that works best is not a website.
Honestly, it depends on the thing and on you. Some of what is here leans on techniques with real evidence behind them, some of it is closer to a nice idea that helps because it gives your head something dull to do, and we try to say which is which on each page.
What we will not do is tell you something is clinically proven when it is not. A sleep site that oversells itself is just another thing keeping you up.
There are no accounts, so there is nothing to log into and nothing tying any of this to you. Your settings, the voice you picked, how long you say you take to fall asleep, live in your own browser and never leave it.
The one exception is deliberate: if you queue a sound or leave an email address, you have sent us that on purpose, and the queue is public by design so everybody sees the same list.
There is no catch and no paywall, mostly because there is nothing expensive to pay for. The sounds are generated in your browser rather than streamed, so there are no files to host and no licences to buy.
If that changes we will say so plainly rather than quietly putting a wall in front of something that used to be free.
Not medical advice. If you really can’t sleep, go see someone real. We just have the rain sounds.
Have a nice sleep, bro.
