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.
