详细描述

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

特性文档编制

attenuationModel : string

This property specifies which attenuation model this sound will apply.

category : string

This property specifies which AudioCategory this sound belongs to.

cone.innerAngle : real

This property holds the innerAngle for Sound definition. The range is [0, 360] degree. There is no directional attenuation within innerAngle.

cone.outerAngle : real

This property holds the outerAngle for Sound definition. The range is [0, 360] degree. All audio output from this sound will be attenuated by outerGain outside outerAngle.

cone.outerGain : real

This property holds attenuation value for directional attenuation of this sound. The range is [0, 1]. All audio output from this sound will be attenuated by outerGain outside outerAngle .

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.

addPlayVariation ( PlayVariation playVariation )

添加给定 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);
    }
}
