Public Member Functions
	MP3DecoderMAD (libmad::MP3DataCallback dataCallback, libmad::MP3InfoCallback infoCB=nullptr)
	MP3DecoderMAD (Print &mad_output_streamput, libmad::MP3InfoCallback infoCB=nullptr)
AudioInfo	audioInfo ()
libmad::MadAudioInfo	audioInfoEx ()
	Provides the last valid audio information.
void	begin ()
	Starts the processing.
virtual void	begin (AudioInfo info)
libmad::MP3DecoderMAD *	driver ()
void	end ()
	Releases the reserved memory.
virtual bool	isResultPCM ()
	If true, the decoding result is PCM data.
	operator bool ()
	Returns true as long as we are processing data.
void	setAudioDataCallback (libmad::MP3DataCallback cb)
	Defines the callback which receives the decoded data.
virtual void	setAudioInfo (AudioInfo from) override
	for most decoders this is not needed
void	setInfoCallback (libmad::MP3InfoCallback cb)
	Defines the callback which receives the Info changes.
virtual void	setNotifyAudioChange (AudioInfoSupport &bi)
	Registers an object that is notified if the audio format is changing.
virtual void	setOutput (AudioOutput &out_stream)
	Defines where the decoded result is written to.
virtual void	setOutput (AudioStream &out_stream)
	Defines where the decoded result is written to.
void	setOutput (Print &out)
	Defines where the decoded result is written to.
size_t	write (const void *data, size_t len)
	Makes the mp3 data available for decoding: however we recommend to provide the data via a callback or input stream.
size_t	write (void *data, size_t len)
	Makes the mp3 data available for decoding: however we recommend to provide the data via a callback or input stream.
