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"
        }

        AudioSample {
            name:"explosion02"
            source: "explosion-02.wav"
        }

        Sound {
            name:"explosion"
            playType: Sound.Random
            PlayVariation {
                sample:"explosion01"
                minPitch: 0.8
                maxPitch: 1.1
            }
            PlayVariation {
                sample:"explosion02"
                minGain: 1.1
                maxGain: 1.5
            }
        }
    }

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, )

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".
