...unless it does! I agree with your other points. One could run a compressor on an audio output easily enough. I have considered it. Video matters when there is show and tell. In a manufacturing sense, having video makes for a 5x meeting. People can consult drawings, identify features, express intent and query others about a part that is only rivaled by an actual conference room.

Add video and people developing their own can contribute and absorb that ongoing skill much better and that is good for everyone.
