Soundscapes
Rain, waves, wind in trees, a stream, a summer night, dawn birds, and four kinds of soft noise. Pick up to three and mix them, set the volume, and add a sleep timer if you like.
How these sounds are made
Every sound here is made by this browser while it plays, from noise and simple tones shaped to sound like rain, surf, wind, water, insects, and birds. Nothing is recorded and nothing is downloaded, so it plays offline once this page has loaded.
Sound starts only when you tap Play or a sound. Changes fade in and out. The sleep timer fades the sound over its last minute and then stops it, even if the page is in the background.
Keep the volume low enough that you can still hear the room around you.
