@millions-hair-24956 I have this scenario where I create an agent and use the straight forwarder to forward multiple transcriptions and multiple audio tracks to be more specific I have created an agent that takes an audio track and return transcription of the text with transcription of translation for multiple languages and and return multiple audio tracks Can i on my web app that I am using react next app with livekit sdk to intercept these audio tracks and mute them and keep one only unmuted ??

Yes, you can intercept and manage audio tracks in your React Next.js app using the LiveKit SDK. You can use the

useTracks

hook to access the audio tracks and then control their mute state. To mute all but one track, iterate over the tracks and set the

setEnabled

method to

false

for the tracks you want to mute, and

true

for the one you want to keep unmuted. Here's a basic example of how you might achieve this:

import { useTracks } from '@livekit/components-react';

function ManageAudioTracks() {
  const tracks = useTracks([Track.Source.Microphone]);

  const muteAllExceptOne = (trackToKeepUnmuted) => {
    tracks.forEach((track) => {
      if (track !== trackToKeepUnmuted) {
        track.setEnabled(false);
      } else {
        track.setEnabled(true);
      }
    });
  };

  return (
    <div>
      {/* Your UI components */}
    </div>
  );
}

@millions-hair-24956 can i use room.TrackSubscribed ? or this is different ?

Yes, you can use the

RoomEvent.TrackSubscribed

event to handle when a new track is subscribed in the room. This event is useful for intercepting tracks as they are subscribed, allowing you to perform actions such as muting or processing the track. Here's a basic example of how you might use `RoomEvent.TrackSubscribed`:

import { connect, RoomEvent } from 'livekit-client';

async function connectToRoom() {
  const room = await connect('ws://your_host', 'your_token');
  
  room.on(RoomEvent.TrackSubscribed, (track, publication, participant) => {
    // Handle the subscribed track
    if (track.kind === 'audio') {
      // Mute or process the track as needed
      publication.setEnabled(false); // Example: Mute the track
    }
  });
}

connectToRoom();

@millions-hair-24956 how can i unmute one of the tracks and keep other muted ?

To unmute one track while keeping others muted, you can use the

setEnabled

method on the

TrackPublication

object for each track. Here's how you can achieve this: 1. Listen for Track Subscriptions: Use the

RoomEvent.TrackSubscribed

event to handle when tracks are subscribed. 2. Mute All Tracks Initially: Set all tracks to be muted by default. 3. Unmute a Specific Track: Use the

setEnabled(true)

method on the

TrackPublication

of the track you want to unmute. Here's an example:

import { connect, RoomEvent } from 'livekit-client';

async function connectToRoom() {
  const room = await connect('ws://your_host', 'your_token');
  
  room.on(RoomEvent.TrackSubscribed, (track, publication, participant) => {
    if (track.kind === 'audio') {
      // Mute all tracks initially
      publication.setEnabled(false);
    }
  });

  // Function to unmute a specific track
  function unmuteTrack(trackSid) {
    const publication = room.localParticipant.getTrackPublication(trackSid);
    if (publication) {
      publication.setEnabled(true); // Unmute the specific track
    }
  }

  // Example usage: unmute a track with a specific SID
  unmuteTrack('specific_track_sid');
}

connectToRoom();

@millions-hair-24956 does the sid is ispecified for every track gotten by track or each time it is changing with every track gotten ?
