Public Member Functions

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
 
int available () override
 
int availableForWrite () override
 
virtual bool begin ()
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
void end () override
 
virtual void flush () override
 
virtual float getByteFactor ()=0
 
virtual PrintgetPrint ()
 
virtual StreamgetStream ()
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
 operator bool ()
 
size_t readBytes (uint8_t *data, size_t size) 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 setNotifyActive (bool flag)
 Deactivate/Reactivate automatic AudioInfo updates: (default is active)
 
virtual void setOutput (AudioOutput &print)
 
virtual void setOutput (Print &print) override
 Defines/Changes the output target.
 
virtual void setStream (AudioStream &stream)
 
virtual void setStream (Stream &stream) override
 Defines/Changes the input & output.
 
virtual size_t write (const uint8_t *buffer, size_t size) override
 
virtual size_t write (uint8_t ch) override
 
virtual void writeSilence (size_t len)
 Writes len bytes of silence (=0).
