Center Surround Sound (NodeMCU)
When settling speakers in to place, you are idealizing that you will always sit dead center .. yet in our more lethargic reality, we lounge off-center. As consequence, you cease being the center of the speaker array .. until now ..

1. Intended to create an app with MIT App Inventor .. how-ever .. per the previous HaD FP (Voice Kitchen Faucet) .. it was decided to employ an alternative favored open source (-ish) voice command software purely as demonstration.
2. Adding additional speakers merely requires copy-paste and if-statement modifications .. tho ideally a more advanced 'find' function upon installation would be coded.
3. Variances of % may depend on wattage (See #4)
4. Higher voltage systems would subsequently require HV digital potentiometers (AD7376)
5. Why is this .. not already a thing?!
