ActiveSpeakerDetector

All Implemented Interfaces:
```
public interface ActiveSpeakerDetector<T>

                    
```
Represents an algorithm for the detection/identification of the active/dominant speaker/participant/endpoint/stream in a multipoint conference.
Implementations of ActiveSpeakerDetector get notified about the (current) audio levels of multiple audio streams (identified by their synchronization source identifiers/SSRCs) via calls to levelChanged and determine/identify which stream is dominant/active (in terms of speech). When the active stream changes, listeners registered via addActiveSpeakerChangedListener are notified.

  - addActiveSpeakerChangedListener
```
 abstract void addActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)
```
    Adds a listener to be notified by this active speaker detector when the active stream changes.
    
    Parameters:
    
    listener - the listener to register with this instance for notifications about changes of the active speaker
  - levelChanged
```
 abstract SpeakerRanking levelChanged(T id, int level)
```
    Notifies this ActiveSpeakerDetector about the latest/current audio level of a stream/speaker identified by a specific synchronization source identifier/SSRC.
    
    Parameters:
    
    level - the latest/current audio level of the stream/speaker with the specified ssrc
    
    Returns:
    
    The current energy rank and related data.
  - removeActiveSpeakerChangedListener
```
 abstract void removeActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)
```
    Removes a listener to no longer be notified by this active speaker detector when the active stream changes.
    
    Parameters:
    
    listener - the listener to unregister with this instance for notifications about changes of the active speaker
