Nature Sound Mixer: Sleep

Build the ambience that fits your moment. Sleep, focus, work, rest — your call.

Craft your own calm — to relax, focus or drift off to sleep. Mix 35 field-recorded nature sounds — rain, ocean waves, forest, thunder, campfire — plus white, brown, pink and green noise, adjust every level, and place each sound around you — wind to the left, rain ahead, birds further away (best with headphones). Set a sleep timer, lock your phone, and keep playback going in the background. Everything works offline.
