When a gamemaster uses background music and nature sounds in his game he always has to select carefully to make sure that the background sounds fit the situation he describes. At Naturesoundsfor.me you can create your own background sound composition by selecting and adding elements like fire, thunder, rain, bird sounds, animal sounds and many more.

For example if you need the sound of a boatman who crosses the characters over a river, heavy rain and thunder complete the sound scenery, then simply choose the three patterns, adjust the volume of each element and create your own background or scenery sound. You can save your creation as a WAV file or you can also create a link to your composition.

UPDATE

A new feature was added to the Free Nature Sounds. It is now possible to fade in/out selected sounds in various time sequences. This feature will add more diversity to your compositions. Example
