	Add an additional AudioOutput output.

void	add (AudioStream &stream)
	Add an AudioStream to the output.

void	add (Print &print)

virtual void	addNotifyAudioChange (AudioInfoSupport &bi)
	Adds target to be notified about audio changes.

virtual AudioInfo	audioInfo () override
	provides the actual input AudioInfo

virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

virtual int	availableForWrite () override

virtual bool	begin ()

virtual bool	begin (AudioInfo info)

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

virtual void	end ()

void	flush ()

virtual bool	isDeletable ()
	If true we need to release the related memory in the destructor.

bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.

	operator bool ()

virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.

void	setAudioInfo (AudioInfo info)
	Defines the input AudioInfo.
