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
virtual int availableForWrite () override
bool begin ()
bool begin (AudioMP34DT05Config cfg)
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
AudioMP34DT05Config defaultConfig (int mode=RX_MODE)
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 setNotifyActive (bool flag)
 Deactivate/Reactivate automatic AudioInfo updates: (default is active)
virtual size_t write (const uint8_t *data, size_t len) override
virtual size_t write (uint8_t ch) override
virtual void writeSilence (size_t len)
 Writes len bytes of silence (=0).

◆ onReceive()

void onReceive ( )

for some strange reasons available provides only the right result after onReceive, so unfortunately we need to use an additional buffer
