 AdapterAudioStreamToAudioOutput (AudioStream &stream)
 
virtual void addNotifyAudioChange (AudioInfoSupport &bi)
 Adds target to be notified about audio changes.
 
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 availableForWrite () override
 
bool begin () override
 
virtual bool begin (AudioInfo info)
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
void end () override
 
virtual void flush ()
 
virtual bool isDeletable ()
 If true we need to release the related memory in the destructor.
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
 operator bool () override
 
virtual bool removeNotifyAudioChange (AudioInfoSupport &bi)
 Removes a target in order not to be notified about audio changes.
 
void setAudioInfo (AudioInfo info) override
 Defines the input AudioInfo.
 
void setNotifyActive (bool flag)
 Deactivate/Reactivate automatic AudioInfo updates: (default is active)
