Application Development with Qt Creator - Second Edition

Playing audio clips and sound effects

Qt Quick provides the SoundEffect type to play short sound effects with a minimum latency. This is especially good for things such as button click sounds, virtual keyboard sounds, and alert tones as part of a rich and engaging multimedia experience. Using it is straightforward; you provide the type with a source field and call its play method to start the playback, as follows:

import QtQuick 2.3
import QtMultimedia 5.0

Text {
    text: "Click Me!";
    font.pointSize: 24;
    width: 150; height: 50;

    SoundEffect {
        id: playSound
        source: "soundeffect.wav"
    }
    MouseArea {
        id: playArea
        anchors.fill: parent
        onPressed: { playSound.play() }
    }
}

Here, SoundEffect will play the contents of the soundeffect.wav file stored in the application's ...
