hi

getVolume and getPan do not do what you wish they do. They return the value of a parameter for playing back sampled or synthesized sound, like the volume or pan knob on a mixer.

You want something that analyzes incoming sound and makes a value judgment about it, which is more complicated and inexact. Assuming there isn't some new analysis modules in the new minim that I don't know about, you'll have to write your own, here's a couple very basic ideas to get you rolling:

for volume: take the last X samples in the buffer and take the average of their absolute values. A small value for X makes this number very responsive and punchy (and jittery), while a larger X makes this number respond more slowly and smoothly. And remember that our ear does not interpret amplitude linearly as volume, so you'll probably want to do a square root of the results to get something that roughly correlates to a volume measurement.

for pan: take the volume measurements of the two inputs and compare their relative volumes to compute which side has more power.
