How can I reduce echo in the class?
- A USB headset is recommended. External or built-in speakers or webcams with
microphone can pick up additional noise and can cause echo.
- Virtual Classroom automatically adjusts audio. We recommend you keep this option checked.
(You see this option in microphone test).
- If echo is suspected from an attendee, ask the attendee to lower his or her
- Uncheck Microphone Boost option.
Can’t hear properly or there is a lag/dropped words in the voice or jerky video?
- Lag or dropped words in the voice happen due to slow Internet connection or
due to high CPU usage.
- Check bandwidth and Internet connection test listed above.
- Close a few or all applications that you don’t require in the class to free
No one can hear me?
- Test your microphone in audio tests; make sure your mic is plugged in and
- Check your microphone is not muted.
- If a particular attendee is not able to hear you, ask him or her to check
- If you are an attendee, make sure that the presenter has allowed you mic.
