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	available () override
	Returns the available bytes in the buffer: to be avoided.

virtual int	availableForWrite ()

virtual bool	begin ()

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

virtual void	end ()

virtual void	flush () override

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

virtual	operator bool ()

size_t	readBytes (uint8_t *data, size_t len) override

virtual size_t	readSilence (uint8_t *buffer, size_t length)
	Source to generate silence: just sets the buffer to 0.

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

virtual void	setAudioInfo (AudioInfo newInfo) override
	Defines the input AudioInfo.

void	setConverter (BaseConverter &cnv)

void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)

void	setOutput (Print &out)
	Defines/Changes the output target.

void	setStream (Stream &stream)
	Defines/Changes the input & output.

virtual size_t	write (const uint8_t *data, size_t len)

virtual size_t	write (uint8_t ch) override

virtual void	writeSilence (size_t len)
	Writes len bytes of silence (=0).
