}Sound instances can be grouped together by specifying the category property. When you change the volume of a category, all audio output from related instances will be affected as well.
Note: there will always be an AudioCategory named default whether you explicitly define it or not. If you do not specify any category for a Sound, it will be grouped into the default category.
