If you do not have a lot of choice over what microphone you will have to use with video calls, there are a few environmental factors to consider that can help your outgoing audio quality. Larger rooms, for example, tend to be more echoey. Likewise, rooms with flat walls with few furnishings, floor coverings or wall hangings will produce more echoes. Smaller rooms with irregular wall surfaces, e.g., rooms lined with bookshelves, carpeted or hung with pictures, will yield a clearer sound with less reverberation. If your computer set up allows the flexibility to move, use Zoom to record yourself in different areas to find the area with the best acoustics that will yield the desired sound quality for your listeners.
