SoundInstance

Detailed Description

This type is part of the QtAudioEngine 1.0 module.

There are two ways to create SoundInstance objects. You can obtain it by calling newInstance method of a Sound:

 import QtQuick 2.0
 import QtAudioEngine 1.0

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

     AudioEngine {
         id:audioengine

         AudioSample {
             name:"explosion01"
             source: "explosion-01.wav"
         }

         Sound {
             name:"explosion"
             PlayVariation {
                 sample:"explosion01"
             }
         }
     }

     property variant soundEffect: audioengine.sounds["explosion"].newInstance();

     MouseArea {
         anchors.fill: parent
         onPressed: {
             root.soundEffect.play();
         }
     }
 }

Or alternatively, you can explicitly define SoundInstance outside of AudioEngine for easier qml bindings:

 import QtQuick 2.0
 import QtAudioEngine 1.0

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

     AudioEngine {
         id:audioengine

         AudioSample {
             name:"explosion01"
             source: "explosion-01.wav"
         }

         Sound {
             name:"explosion"
             PlayVariation {
                 sample:"explosion01"
             }
         }
     }

     Item {
         id: animator
         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
             }

         }
     }

     SoundInstance {
         id:soundEffect
         engine:audioengine
         sound:"explosion"
         position:Qt.vector3d(animator.x, animator.y, 0);
     }

     MouseArea {
         anchors.fill: parent
         onPressed: {
             soundEffect.play();
         }
     }
 }
