To download a file, scroll down past the playlists to the individual sound files.
Underneath each soundscape to the left is a row of 5 buttons. From left, you can "Like" a file, repost it to social media, add it to your own playlist, share it with a friend, or download - that's the downward arrow.
Click on this button, and a window will pop up to save the file. You can choose where to save it, then click "Save." The file is now yours to use (but not to make money)!
