Detailed Description

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

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

     AudioEngine {
         id:audioengine

         AttenuationModelInverse {
            name:"linear"
            start: 20
            end: 500
            rolloff: 1.5
         }

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

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

Attenuation factor is calculated as below:

distance: distance from sound to listener d = min(max(distance, start), end); attenuation = start / (start + (d - start) * rolloff);
