## Detailed Description

AttenuationModelLinear must be defined inside AudioEngine or be added to it using AudioEngine.addAttenuationModel() if AttenuationModelLinear is created dynamically.

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

          AudioEngine {
              id:audioengine

              AttenuationModelLinear {
                 name:"linear"
                 start: 20
                 end: 180
              }

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

              Sound {
                  name:"explosion"
                  attenuationModel: "linear"
                  PlayVariation {
                      sample:"explosion"
                  }
              }

## Property Documentation

end : real

This property holds the end distance. There will be no sound hearable if the distance from sound to listener is larger than this. The default value is 1.

name : string

This property holds the name of AttenuationModelLinear, must be unique among all attenuation models and only defined once.

start : real

This property holds the start distance. There will be no attenuation if the distance from sound to listener is within this range. The default value is 0.
