    \class QPlatformAudioSource
    \brief The QPlatformAudioSource class provides access for QAudioSource to access the audio
    device provided by the plugin.

    \ingroup multimedia
    \inmodule QtMultimedia

    QAudioDeviceInput keeps an instance of QPlatformAudioSource and
    routes calls to functions of the same name to QPlatformAudioSource.
    This means that it is QPlatformAudioSource that implements the
    audio functionality. For a description of the functionality, see
    the QAudioSource class description.
