A package fro Amazon arrived today, an articulated microphone stand.
I started up Zoom to check the audio and video (wondering how much it intruded into the view) and was amazed to note that until I placed my hand or some other body part behind the microphone, it was invisible to Zoom even when it was only six inches away from my mouth.
Most impressive. The audio is also without any booming or echoes, which is why I bought the thing in the first place.
