bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.
virtual	operator bool () override
	checks if the class is active
virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.
void	setInput (Stream &inStream)
void	setNotifyActive (bool flag)

Stream Interface: Decode directly by taking data from the stream. This is more efficient then feeding the decoder with write: just call copy() in the loop
