#include <AudioOutput.h>
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 | |
virtual int | availableForWrite () override |

virtual bool | begin (AudioInfo info) |
virtual void | clearNotifyAudioChange () |
Deletes all change notify subscriptions. | |
virtual void | end () |
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 () | |
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) | |
