Ok, really good points.

Taking onboard what you said, a system could work to match sound volume with direction to see in a higher resolution.

I.e. It would superimpose all color in range together with those closer to the center having a higher amplitude. So the colors directly ahead would be player louder and peripheral colors played quietly.

Or perhaps this is how it works already....

Roughly how many different notes could you hear at a time?
