Migrate from Dolby.io to LiveKit.io

// Example: Integrating OpenAI Whisper with LiveKit
import { Room, RoomEvent } from 'livekit-client';
import { AudioProcessor } from './audio-processor';
import { WhisperTranscriber } from './whisper-transcriber';

// Set up LiveKit room
const room = new Room();

// Initialize transcriber
const transcriber = new WhisperTranscriber({
  apiKey: 'your-openai-api-key',

// Process audio for transcription
room.localParticipant.on(RoomEvent.TrackPublished, async (publication) => {
  if (publication.kind === 'audio') {
    const audioTrack = publication.track;
    const processor = new AudioProcessor(audioTrack);
    
    // Process audio chunks and send to Whisper
    processor.onAudioChunk((audioChunk) => {

        console.log('Transcription:', text);
        // Use the transcription in your application
      });
    });
  }

// Example: Integrating ElevenLabs TTS with LiveKit

  // Publish the track to the room
  await room.localParticipant.publishTrack(audioTrack);
  
  // Start playing the audio
  audioStreamer.play();
