Detailed Description

Sound can be accessed through QtAudioEngine::AudioEngine::sounds with its unique name and must be defined inside AudioEngine or be added to it using AudioEngine.addSound() if Sound is created dynamically.

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

    AudioEngine {
        id:audioengine

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

Property Documentation

attenuationModel : string

This property specifies which attenuation model this sound will apply.


category : string

This property specifies which AudioCategory this sound belongs to.


name : string

This property holds the name of Sound, must be unique among all sounds and only defined once.


playType : enumeration

This property holds the playType. It can be one of:

  • Random - randomly picks up a play variation when playback is triggered
  • Sequential - plays each variation in sequence when playback is triggered

The default value is Random.


Method Documentation

addPlayVariation(PlayVariation playVariation)

Adds the given playVariation to sound. This can be used when the PlayVariation is created dynamically:

import QtAudioEngine 1.1

AudioEngine {
    id: engine

    Component.onCompleted: {
        var playVariation = Qt.createQmlObject('import QtAudioEngine 1.1; PlayVariation {}', engine);
        playVariation.sample = "sample";
        playVariation.minPitch = 0.8
        playVariation.maxPitch = 1.1

        var sound = Qt.createQmlObject('import QtAudioEngine 1.1; Sound {}', engine);
        sound.name = "example";
        sound.addPlayVariation(playVariation);
        engine.addSound(sound);
    }
}

Returns a new SoundInstance.


play(position, velocity, direction, gain, pitch)

Creates a new SoundInstance and starts playing with specified position, velocity, direction, adjusted gain and pitch.


play(position, velocity, gain, pitch)

Creates a new SoundInstance and starts playing with specified position, velocity, adjusted gain and pitch. Direction is set to "0,0,0".


play(position, gain, pitch)

Creates a new SoundInstance and starts playing with specified position, adjusted gain and pitch. Direction and velocity are all set to "0,0,0".


play(position, velocity, direction, gain)

Creates a new SoundInstance and starts playing with specified position, velocity, direction and adjusted gain.


play(position, velocity, gain)

Creates a new SoundInstance and starts playing with specified position, velocity and adjusted gain. Direction is set to "0,0,0".


play(position, gain)

Creates a new SoundInstance and starts playing with specified position and adjusted gain. Direction and velocity are all set to "0,0,0".


play(position, velocity, direction)

Creates a new SoundInstance and starts playing with specified position, velocity and direction.


play(position, velocity)

Creates a new SoundInstance and starts playing with specified position and velocity. Direction is set to "0,0,0".


play(position)

Creates a new SoundInstance and starts playing with specified position. Direction and velocity are all set to "0,0,0".


play(gain, pitch)

Creates a new SoundInstance and starts playing with the adjusted gain and pitch. Position, direction and velocity are all set to "0,0,0".


play(gain)

Creates a new SoundInstance and starts playing with the adjusted gain. Position, direction and velocity are all set to "0,0,0".


play()

Creates a new SoundInstance and starts playing. Position, direction and velocity are all set to "0,0,0".
