The Master-Mixer Console is a mixing console that groups a variety of bus properties into one view so that you can create the final mix of your game audio. When you are connected to a game, you can audition and then tweak the properties of your audio and motion as it is being played back in game in real time.
You can also monitor specific information related to the objects that are routed through the various busses in your project, including:

Duck - Indicates when a bus is ducked.
BG - Indicates that a bus is tied to the background music option.
Bypass - Indicates that the Bypass All option is selected for a particular bus.
Effect - Indicates the particular Effect or series of Effects that have been applied to the bus.
