Also that display is a good one to monitorive PA sound. Or of a system with various inputs. For example, a stereo signal with little channel separation has a distinctive pattern approaching a straight line as you get to monaural. The tilt of the line indicates balance-a 45 degree slope equals equal output levels. Left or right slopes show whether the channels are in or out of phase. I used to use this a a stage monitor because you could quickly see what had gone wrong when it did. And whether what you did to fix it worked.
