Detailed Description

This type is part of the QtAudioEngine 1.0 module.

AttenuationModelInverse must be defined inside AudioEngine.

import QtQuick 2.0
import QtAudioEngine 1.0


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);
