What's new

New Volume Hooks and BarVisualizer

• The useTrackVolume hook returns the volume of an audio track.

let volume = useTrackVolume(audioTrack); // returns a number between 0-1

• The useMultibandTrackVolume hook returns the volume of an audio track across multiple frequency bands.

let volumes = useMultibandTrackVolume(audioTrack); // returns an array of numbers between 0-1

• The BarVisualizer component can be used to quickly get a visual representation of an audio track.

<BarVisualizer trackRef={audioTrack}/>

It can also be combined with the useVoiceAssistant hook to automatically transition the appearance based on the agent state:

function SimpleVoiceAssistant() {
  const { state, audioTrack } = useVoiceAssistant();
  return (
   <BarVisualizer
     state={state}
     trackRef={audioTrack}
   />
  );
}

Native APIs for audio processing

New apis are available at the native level for processing the audio:

// iOS
#import "LKAudioProcessingManager.h"
LKAudioProcessingManager *apm = LKAudioProcessingManager.sharedInstance.audioProcessingModule;

// Android
import com.livekit.reactnative.LiveKitReactNative;
AudioProcessingController apc = LiveKitReactNative.audioProcessingController;
