Adjust the Volume (Web SDK 3.x)

Introduction

The Agora RTC SDK enables you to manage the volume of the recorded audio or of the audio playback according to your actual scenario. For example, to mute a remote user in a one-to-one call, you can set the audio playback volume as 0.

Implementation

Before adjusting the audio volume, ensure that you have implemented the basic real-time communication functions in your project. For details, see Start a Call or Start Interactive Live Streaming.

Sample code

Adjust the playout volume

 client.on("stream-subscribed", function(evt){
  var stream = evt.stream;
  // Sets the volume of the remote stream to 50.
  stream.setAudioVolume(50);
 });

Mute the remote user

 client.on("stream-subscribed", function(evt){
  var stream = evt.stream;
  // Mutes the remote stream.
  stream.setAudioVolume(0);
 });
