Detailed Description

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

 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:

 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 cases.
