Ambient Sounds
Mix rain, waves, wind, fire, a fan and colored noise into your own background sound.
All sounds are generated live in your browser. They keep playing when you switch tabs.
How to use
Press Play, then switch sounds on or off and set the volume of each one. The master slider changes the overall level of the mix.
Presets set up a mix in one click: Focus, Sleep and Rain on a window. You can change anything afterwards, and your mix is remembered for your next visit.
Set the sleep timer to 15, 30, 60 or 90 minutes. The sound fades out over the final minute and then stops.
Every sound is synthesized live by your browser with the Web Audio API, so nothing is downloaded. Rain drops, waves, gusts and crackles are randomized, so the mix does not fall into an obvious loop.
FAQ
What is the difference between white, pink and brown noise?
White noise has equal power at every frequency and sounds bright, like a hiss. Pink noise loses half its power with each octave up, which sounds softer and closer to steady rain. Brown noise falls off faster still and sounds deep, like a distant waterfall or strong wind.
Does the sound keep playing in a background tab?
Yes. On desktop browsers the sound continues when you switch tabs or minimize the window. On phones the system may pause web audio when the screen locks or the browser goes to the background, depending on the device and browser.
Can I use it to fall asleep?
Choose the Sleep preset or your own mix, keep the volume low and set the sleep timer. The sound fades out over the last minute instead of stopping abruptly.
Is any audio downloaded or recorded?
No. The sounds are built from random noise and filters inside your browser. The page does not download audio files and never uses your microphone.
Why can't I hear anything?
Browsers only start audio after you press a button on the page, so press Play first. If you still hear nothing, check the media volume of your device and, on an iPhone, the silent mode switch.
