AudioListener

Detailed Description

This type is part of the QtAudioEngine 1.0 module.

AudioListener will have only one global instance and you can either access it through the listener property of AudioEngine:

 import QtQuick 2.0
 import QtAudioEngine 1.0

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

     AudioEngine {
         id:audioengine
         listener.up:"0,0,1"
         listener.velocity:"0,0,0"
         listener.direction:"0,1,0"
         listener.position:Qt.vector3d(observer.x, observer.y, 0);
     }

     Item {
         id: observer
         x: 10 + observer.percent * 100
         y: 20 + observer.percent * 80
         property real percent: 0
         SequentialAnimation on percent {
             loops: Animation.Infinite
             running: true
             NumberAnimation {
             duration: 8000
             from: 0
             to: 1
             }

         }
     }
 }

or alternatively, by defining an AudioListener outside AudioEngine:

 import QtQuick 2.0
 import QtAudioEngine 1.0

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

     AudioEngine {
         id:audioengine
         listener.up:"0,0,1"
         listener.velocity:"0,0,0"
         listener.direction:"0,1,0"
     }

     AudioListener {
         engine:audioengine
         position: Qt.vector3d(observer.x, observer.y, 0);
     }

     Item {
         id: observer
         x: 10 + observer.percent * 100
         y: 20 + observer.percent * 80
         property real percent: 0
         SequentialAnimation on percent {
             loops: Animation.Infinite
             running: true
             NumberAnimation {
             duration: 8000
             from: 0
             to: 1
             }

         }
     }
 }

This separate AudioListener definition is allowed to make qml bindings easier in some case.
