White Noiseflat static that masks everything else
Pink Noisesofter than white, like rain behind a window
Brown Noiselower and deeper — the earth breathing
Rainfine rain on the roof and leaves
Winda draft through the window, slowly
Wavesone layer after another, reaching the shore
Campfirewood splitting softly, sparks jumping

Every sound is synthesized live in your browser: white, pink and brown noise are generated by algorithms; rain, wind and waves are filters slowly pushing the noise around; the campfire is brown noise with random crackles. Nothing is uploaded, nothing leaves your machine, and the last minute fades out on its own when the timer ends.
