how to get audio in server when i open the mic

Thanks for reaching out, Vishal. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
I'm glad you're reaching out about receiving audio on the server when a user opens their microphone in LiveKit. Let's walk through the steps together: 1. Client-Side Setup: First, make sure to enable the microphone by using
setMicrophoneEnabled(true)
. This will publish the audio track to the room. Also, double-check that the microphone permissions are granted on the device to avoid any hiccups. 2. Server-Side Audio Processing: On the server side, you'll want to use a server SDK to subscribe to the audio track. For example, if you're using the Go SDK, the
OnTrackSubscribed
callback is your friend for accessing the audio stream. If you're working with Python,
RoomInput
can help you process audio frames in real time. 3. Optional Pre-Connect Audio: If your use case requires it, you can capture audio even before the participant fully joins the room by using the
PreConnectAudioHandler
. This is handy for more advanced scenarios. 4. Audio Processing: To enhance the audio quality, consider applying features like echo cancellation or noise suppression using an Audio Processing Module (APM), if that fits your needs. If you'd like, I can provide detailed code examples or help you troubleshoot any part of this process. Just let me know—I’m here to help!

import { Room } from "@livekit/rtc-node"; import config from "../Config/Keys.config.js"; export async function personaConnect(roomName, token) { console.log(
:robot_face: Persona connecting to ${roomName}...
); const room = new Room(); try { await room.connect(config.livekit.url, token); console.log(
:robot_face: Persona joined room: ${room.name}
); // Listen to events room.on("participantConnected", (participant) => { console.log(
:headphones: Persona sees participant: ${participant.identity}
); }); room.on("trackSubscribed", (track, publication, participant) => { console.log(
:headphones: Persona subscribed to ${participant.identity}'s track
); }); room.on("participantDisconnected", (participant) => { console.log(
:wave: ${participant.identity} left
); }); room.on("disconnected", () => { console.log(" Persona disconnected"); }); } catch (err) { console.error(" Persona failed to join room:", err.message); } }

I'm happy to guide you through using the LiveKit JavaScript SDK to connect to a room and handle events. Just follow these simple steps: 1. Install the SDK: Start by installing the LiveKit SDK with npm:
npm install @livekit/client
2. Connect to a Room: Next, create a new
Room
instance and connect using your server URL and access token:
Copy code
import { connect } from '@livekit/client';

const room = await connect('your-server-url', 'your-access-token');
console.log('Connected to room:', room.name);
3. Handle Events: You can easily manage room events with event listeners: ◦ `participantConnected`: This event fires when someone joins the room:
Copy code
room.on('participantConnected', (participant) => {
  console.log('Participant connected:', participant.identity);
});
◦ `trackSubscribed`: This happens when you subscribe to a track:
Copy code
room.on('trackSubscribed', (track, publication, participant) => {
  console.log('Track subscribed:', track.kind, 'from', participant.identity);
  const element = track.attach();
  document.body.appendChild(element);
});
◦ `participantDisconnected`: And this event triggers when someone leaves:
Copy code
room.on('participantDisconnected', (participant) => {
  console.log('Participant disconnected:', participant.identity);
});
1. Disconnect: When you're ready to leave the room, just call:
room.disconnect();
If you have any questions or want me to walk you through more examples, please don’t hesitate to ask. I’m here to help!

class to connect to your room:

const room = new Room();
await room.connect('your-server-url', 'your-access-token');
console.log('Connected to room:', room.name);
3. Handle Events: It’s important to listen to key room events like
participantConnected
,
trackSubscribed
, and
participantDisconnected
. Here’s how you can do that:
Copy code
room.on('participantConnected', (participant) => {
  console.log('Participant connected:', participant.identity);
});

room.on('trackSubscribed', (track, publication, participant) => {
  console.log('Track subscribed:', track.kind, 'from', participant.identity);
  const element = track.attach();
  document.body.appendChild(element);
});

room.on('participantDisconnected', (participant) => {
  console.log('Participant disconnected:', participant.identity);
});
4. Disconnect: When you’re ready to leave the room, just call `room.disconnect()`:
room.disconnect();

I'd love to help you with processing the audio on your server! Could you please share a bit more about how you're approaching it? For example: • Are you working with a specific server SDK like Node.js, Go, or Python? • Are you subscribing to the audio track within your server code? • Have you noticed any errors or logs that might hint at issues with track subscription or audio processing? Once I have a clearer picture, I’ll be able to guide you much better. Looking forward to your response!
