[explicit] QcSystemAudio::QcSystemAudio(QObject *parent = nullptr)
The system's audio, child of parent; the audio thread starts with the first sink.
[delete] QcSystemAudio::QcSystemAudio(const QcSystemAudio &)
Copy-constructs an instance of QcSystemAudio. This function is deleted.
[delete] QcSystemAudio::QcSystemAudio(QcSystemAudio &&)
Move-constructs an instance of QcSystemAudio. This function is deleted.
[override virtual] void QcSystemAudio::close()
Reimplements: QcAudioPlatform::close().

Copy-assigns other to this QcSystemAudio instance. This function is deleted.
Member Variable Documentation
const int QcSystemAudio::bufferMilliseconds
Audio the sink keeps buffered: short enough for direct feedback, long enough to ride out a slow frame.
