Sound Ideas ambiences and public places sound effects collections provide long, clean backgrounds against which you can build your story. These collections include both general ambience collections that provide a wide range of environmental sounds as well as more specialized ambience collections that dive deeply into a single location. Longer background ambience tracks provide a more seamless approach to creating the basic environment for a production. Ambience sounds in general allow the visual to match the setting. Creating a courtroom drama without the underlying sounds of a large room with human walla and fidgeting would distract from the story and take the viewer out of the drama. The addition of appropriate ambience tracks allows the viewer to experience courtroom, church, train station, thunderstorm, early morning forest or jungle in which your story is set.
