Confirm audio device selection
Make sure the correct audio device for your mic input and speaker output are selected. For the best Echo Prevention experience, use the input and output from the same hardware. Modern computers generally have a good quality built-in microphone, so we recommend using both your computer's built-in microphone and speakers.
Avoid reverberant rooms
Rooms with little furniture, hard floors or sparse walls tend to have poor acoustics which can reduce the clarity of your voice when talking with others. You can improve the acoustics of a room by adding soft furniture, heavy curtains, or even acoustic panels to the walls or ceiling. In highly reverberant rooms, use headphones along with your computer's built-in microphone for greater voice clarity and reduced echo.
Do not use Bluetooth microphones
Unfortunately, Bluetooth device bandwidth often isn’t sufficient to support full duplex audio. While the use of Bluetooth for headphones is ok, we recommend pairing that with your computer's built-in microphone.
Reduce speaker volume
If you're alone in a room but another meeting participant is complaining of echo, it can likely be resolved by turning down the volume of your speakers. Additionally, we recommend keeping max speaker volume below 75% while talking to prevent unwanted distortion or conflicts with Echo Prevention.
