```
public final class LocalAudioTrack
extends AudioTrack
                    
```
Represents a local audio track (generally using the microphone as input).
This class should not be constructed directly, but rather through LocalParticipant.createAudioTrack.

Constructor Detail

LocalAudioTrack

LocalAudioTrack(String name, AudioTrack mediaTrack, LocalAudioTrackOptions options, AudioProcessingController audioProcessingController, CoroutineDispatcher dispatcher, AudioRecordSamplesDispatcher audioRecordSamplesDispatcher, AudioBufferCallbackDispatcher audioBufferCallbackDispatcher, AudioRecordPrewarmer audioRecordPrewarmer, RTCThreadToken rtcThreadToken)

Method Detail

getFeatures
```
@FlowObservable() final <ERROR CLASS> getFeatures()
```
Changes can be observed by using io.livekit.android.util.flow

getRtcTrack
```
 AudioTrack getRtcTrack()
```
The underlying WebRTC audio track.

getEvents

 final EventListenable<TrackEvent> getEvents()

getName
```
 final String getName()
```

setName
```
 final Unit setName(String name)
```

getKind
```
 final Track.Kind getKind()
```

setKind
```
 final Unit setKind(Track.Kind kind)
```

getSid
```
 final String getSid()
```

setSid
```
 final Unit setSid(String sid)
```

getStreamState

 final Track.StreamState getStreamState()

setStreamState

 final Unit setStreamState(Track.StreamState streamState)

getEnabled
```
 final Boolean getEnabled()
```

setEnabled

 final Unit setEnabled(Boolean enabled)

getStatsGetter

 final Function1<RTCStatsCollectorCallback, Unit> getStatsGetter()

setStatsGetter

 final Unit setStatsGetter(Function1<RTCStatsCollectorCallback, Unit> statsGetter)

getRtcThreadToken

 final RTCThreadToken getRtcThreadToken()

prewarm
```
 final Unit prewarm()
```
Prewarms the audio stack if needed by starting the recording regardless of whether it's being published.

stopPrewarm
```
 final Unit stopPrewarm()
```

addSink
```
 Unit addSink(AudioTrackSink sink)
```
Note: This function relies on us setting JavaAudioDeviceModule.Builder.setSamplesReadyCallback. If you provide your own AudioDeviceModule, or set your own callback, your sink will not receive any audio data.

removeSink
```
 Unit removeSink(AudioTrackSink sink)
```
Removes a previously added sink.

setAudioBufferCallback
```
 final Unit setAudioBufferCallback(AudioBufferCallback callback)
```
Use this method to mix in custom audio.
See MixerAudioBufferCallback for automatic handling of mixing in the provided audio data.

dispose
```
 Unit dispose()
```
Disposes the track. LiveKit will generally take care of disposing tracks for you.
