What's *wrong* is your failure to understand the nature of "audio" signals -- and how a microphone responds to them (which, in turn, relates to how you *monitor* the microphone's output to identify that in which you are interested. Would you look at the *color* of a balloon if trying to determine it's inflated pressure? Would you *count* soil particles if you were interested in quantifying its moisture content? Don't start writing code until you know what -- and HOW -- you are trying to do! (would you purchase thousands of dollars of lumber to build a house before you knew how to do so? What lumber would be required? Whether lumber was a suitable building material for the location of interest?)
