Echo happens when sound from your speakers enters your microphone.
You might not hear it but other participants might be bothered by it.
Here are some instructions to reduce echo in your Live Interview:
- Always prefer headphones over built-in speakers.
- Use moderate volume. When volume is too high it might echo in the microphone.
If you are using Mac:
- Go to System Preferences > Sound > Input
- Enable "Use ambient noise reduction"
Please contact support if echo persists.
