How this rain sound is made
This rain is synthesized, not sampled. Rather than replaying an audio file of an actual storm, the engine builds broadband noise from scratch inside your browser and shapes it in real time until it lands on the texture of falling rain: an even hiss carrying a dense, fine layer of soft droplet transients.
That shaping runs continuously instead of repeating a clip, which is the whole point. A recorded rain track, however long, eventually loops, and most ears catch the seam after a few listens. Generated rain has no seam to catch, because there's no start it ever returns to.
It also means nothing sneaks into the mix by accident. A field recording of rain almost always carries a stray car passing, a dog barking somewhere, or wind knocking the microphone. None of that is here. Just the rain, and nothing else.
What rain sound actually sounds like
Picture steady rain landing on a roof, or a shower running one floor below you: a constant, even hush with a busy, fine texture of droplets scattered across the top of it. There's no heavy thunder mixed in. If you want rumble alongside the rain, that lives in a separate thunderstorm sound built for exactly that.
It sits higher in the spectrum than the deep rumble of brown noise, so it reads as brighter and more textured rather than heavy. Some people describe it as pink noise with detail added: the same even wash, but with rain's countless small patters layered through it.
The overall effect is calm and enveloping rather than dramatic. Nothing spikes or surprises you, and there's no dry patch where the rain briefly lightens before building back up.
Benefits of rain sound
Steady rain is one of the most widely comfortable masking sounds, probably because so many people already associate it with staying in and being allowed to slow down. It covers uneven background noise, like traffic or a noisy building, with something even and predictable instead.
Because the sound never changes character on its own, your ear stops flagging it as something worth paying attention to, which is exactly what lets it fade into the background instead of pulling focus.
- Sleep: masks sudden household and street noise before it breaks your sleep.
- Focus: gives concentration a steady backdrop instead of unpredictable quiet.
- Relaxation: a familiar, cozy sound that makes it easy to wind down.
- Noise masking: covers traffic, neighbors, and other uneven background sound.
- Consistency: never fades, skips, or changes character over hours of play.
How this player shapes the rain
Four controls sit under the player. Tone is a lowpass filter: pull it down for softer, more muffled rain, closer to rain heard through a window, or push it up for a brighter, more present patter. Waves adds a slow swell to the volume, like a gust of rain briefly picking up and easing back. Sleep Timer fades everything out gradually over whatever window you set, instead of cutting off mid-sound.
Underneath those controls, every sound on this player, rain included, runs through a 55 Hz high-pass filter that trims frequencies most phone and laptop speakers can't reproduce cleanly anyway, so you get less rattle and buzz instead of wasted, unheard bass. A limiter sits after that and keeps the signal from clipping or distorting no matter how high you push the volume.
Start the rain and lock your phone: it keeps playing with working lock-screen media controls, so you can pause or adjust volume without unlocking. It runs in any current browser, no app, no account, no ads required. A dedicated app is coming soon but isn't out yet.
How to use rain sound, safely
Start around a moderate volume: loud enough to cover whatever you're masking, not so loud it becomes the loudest thing in the room. Roughly 50 dB or quieter, about the level of a quiet conversation, is a reasonable target for all-night use.
For focus, try it under headphones at low volume while you work. For sleep, set the Sleep Timer rather than leaving it running at full volume all night. Many people don't need it much past falling asleep, and a fade-out is gentler than a hard stop.
If you're using it near a baby, keep the speaker more than 2 meters from the crib and rely on the timer instead of letting it run untouched for hours. This sound is a comfort and masking tool, not a medical treatment. If you notice ear pain, or tinnitus that's new or getting worse, check with a doctor or audiologist rather than relying on masking sound alone.
