Configure volume detection

Implementation

To detect volume levels for the local microphone and remote users, listen to the audioVolume event and call the enableAudioVolumeIndication method.

// Make sure that an AliRtcEngine instance is created.
// Listen to the event.
aliRtcEngine.on('audioVolume', (speakers) => {
  // The array of user volume objects returned by the event.
  speakers.forEach(({ userId, volume }) => {
    // The volume is a numeric value. Valid values: 0 to 100.
    if (userId === '') {
      // If the userId parameter is left empty, the volume is the input volume of the local microphone.
      console.log(`my volume: ${volume}`);
    } else {
      // The volume of the remote user.
      console.log(`user(${userId}) volume: ${volume}`);
    }
  });
});

// Enable volume detection and specify that the audioVolume event is triggered every 1,000 milliseconds.
aliRtcEngine.enableAudioVolumeIndication(1000);

// Disable volume detection by specifying a value less than or equal to 0.
aliRtcEngine.enableAudioVolumeIndication(0);
