Echo is caused by a user's microphone capturing the audio being output by the speaker. Here are a few things you can do to troubleshoot the echo:
Identify the person who’s causing the echo:
- In a one-to-one video call, if you are hearing an echo of your voice, it means that the OTHER user's microphone is causing the echo.
- In a group video call, if you are hearing an echo, check the video window of the call participants who are not speaking but have a green audio wave that is moving. This means the microphone is picking up sound from that speaker and causing echo.
- Use headphones Ask the call participant to turn down their speaker volume, or use headphones instead of speakers (this completely eliminates the possibility of echo). Turning the speaker volume all the way up also causes clipping.
- Mute your microphone If headphones are not available, please ask the person who’s creating echo to mute the microphone when not talking.
Switch devices If you are using the webcam mic, we suggest using the built-in mic and speaker. Sometimes when the microphone and speaker are two different devices - there's clock drift - which would cause echo.
Switch to AECm Toggle between AEC (Audio Echo Cancellation) and AECm in the “Audio and Camera Setup". On PC, go to your local video window, click "gear icon" --> "Audio and Camera Setup". On Mac, select Audio Setup from the VSee menu. Click on the “Advanced” link under Microphone.
- Use speaker phones We recommend the Jabra 410 Speakerphone (or Jabra 510 for BlueTooth support). Make sure the speakerphone is selected in the "Speaker" dropdown menu in "Audio and Camera setup".
