ActiveSpeakerDetector

```
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.

Method Summary

Modifier and Type	Method	Description
`abstract void`	`addActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)`	Adds a listener to be notified by this active speaker detector when theactive stream changes.
`abstract void`	`levelChanged(T id, int level)`	Notifies this ActiveSpeakerDetector about the latest/currentaudio level of a stream/speaker identified by a specific synchronizationsource identifier/SSRC.
`abstract void`	`removeActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)`	Removes a listener to no longer be notified by this active speakerdetector when the active stream changes.

  - addActiveSpeakerChangedListener
```
 abstract void addActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)
```
    Adds a listener to be notified by this active speaker detector when theactive stream changes.
    
    Parameters:
    
    listener - the listener to register with this instance fornotifications about changes of the active speaker
  - levelChanged
```
 abstract void levelChanged(T id, int level)
```
    Notifies this ActiveSpeakerDetector about the latest/currentaudio level of a stream/speaker identified by a specific synchronizationsource identifier/SSRC.
    
    Parameters:
    
    level - the latest/current audio level of the stream/speaker withthe specified ssrc
  - removeActiveSpeakerChangedListener
```
 abstract void removeActiveSpeakerChangedListener(ActiveSpeakerChangedListener<T> listener)
```

    Parameters:
    
    listener - the listener to unregister with this instance fornotifications about changes of the active speaker
