35 catalog sources: 31 ten-minute MP3 masters (including thirteen owner-approved CC0 preview-derived rain, river and ocean arrangements) and four independently recorded shorter CC0 field sources, whose true lengths are disclosed and repeated for continuous playback. Green Noise is available for separate listening review but is not yet owner-approved. Every source has its own identified audio file, and the existing player supports continuous listening where the browser and device permit it.

45 curated presets combining our original sound textures. Each preset can be played without a separate download.
White Noise, Your Way
White noise has equal power per unit bandwidth. Pink and brown noise emphasize lower frequencies in different ways. Choose the sound that you find comfortable. Our sounds are not medical treatments. Natural recordings are marked CC0; other ambient experiments are marked Synthetic. Start at low volume and avoid placing a speaker close to a sleeping infant.
For compatible browsers, our long sound masters use a native continuous audio stream; other browsers use MP3 looping. The sound should continue until Pause/Stop or the selected sleep timer. Background playback depends on iOS and the browser, and system interruptions can still stop audio. The timer uses the device clock; iOS may delay stopping audio while suspended, so it is not a safety cutoff. Dark screen mode only blacks out this webpage.
