Detailed Description

An instance of AudioCategory can be accessed through AudioEngine.categories with its unique name and must be defined inside AudioEngine or be added to it using AudioEngine.addAudioCategory() if AudioCategory is created dynamically.

  Rectangle {
      color:"white"
      width: 300
      height: 500

      AudioEngine {
          id:audioengine

          AudioCategory {
              name: "sfx"
              volume: 0.8
          }

          AudioSample {
              name:"explosion"
              source: "explosion-02.wav"
          }

          Sound {
              name:"explosion"
              category: "sfx"
              PlayVariation {
                  sample:"explosion"
              }
          }
      }

      MouseArea {
          anchors.fill: parent
          onPressed: {
              audioengine.categories["sfx"].volume = 0.5;
          }
      }
  }

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.
