Google announced yesterday that a new feature for Hangouts on Air called Control Room will be rolling out over the next few days. Control Room, which was announced by Google software engineer J.D. Salazar on Google+, will allow all Hangout users to better manage the audio and video levels of a show. The feature lives in a column on the right side of the screen, and uses toggles to show or hide the video and to adjust the audio levels of each individual in the hangout. We knew Control Room was coming — Google teased the feature at an event in October, and Al Jazeera and HuffPost Live have already been trying it out.
