Natural Worlds is a simple application which allows you to play nature sounds through your Mac.
After launching Natural Worlds, you will be immersed in: a bird sanctuary, a thunderstorm, a night-time forest with crickets and owls or anything else you can imagine!
Natural Worlds has a built-in world editor allowing you to modify or create your own unique worlds.
You can add up to 50 environment sounds to each world.
To help eliminate repetition, environment sounds can be grouped together so only one sound within each group plays at one time.
Moreover, you can contribute your created world for everyone to enjoy, by uploading it to the program's website.
