How to Resolve Echo Problems

Symptom

When in a Vonage Video API session, I'm hearing an echo in the audio.

Applies To

• Video API
• Audio Quality
• Echo

Resolution

To reduce echo:

• Reduce the volume of the speakers.
• Reduce the sensitivity of the microphone.
• Use headphones.

To determine the cause of echo:

• Join the session from a different computer. If the echo has reduced, you know that there is an issue with the hardware.
• Join a different chat room. If the echo has reduced, you know that there is an issue with this particular chat room caused by a different user. In this case, selective muting (muting people who are not talking) can help.

Cause

Echo that a user experiences is determined by the hardware (speaker and microphone) and the browser. Some of the reasons that a user might experience echo issues are:

• There are two publishers in the same physical room.
• Two publishers publishing from the same machine.
