Soundscape

Soundscape is an open-source system-tray resident desktop application for playing a mix of sounds, eg natural sounds by animals or wind and water.

The app comes with two sample soundscapes. Use the right mouse button in the main window or on the tray icon to access the application menu, where you can add or remove soundtracks and change their settings.

You can change the volume, loop transition and playback status of each track.
