FAQ
Which sounds can I mix?
Six layers: rain, ocean waves, wind, stream, birds and campfire — each with its own switch and volume. Rain plus birds sounds like a fresh morning; waves plus campfire feels like beach camping. Drag the sliders and build your own mix.
Where do the sounds come from?
Everything is synthesized in real time by your browser — no audio files are loaded, so it starts instantly and even works offline, with no obvious looping. Keep the tab open and your phone awake to keep hearing it.
Can it stop automatically?
Yes — pick a 15, 30 or 60 minute timer and the sound fades out automatically. Set a timer before bed and do not worry about it playing all night.
