Document amplitude range used internally (in AudioSample class?) #75

I teach a class with Processing, and a colleague was surprised because the maximum amplitude she was getting from analyzing a microphone audio in was 0.5.

For me these were not big news, but I remembered finding out this one or two years ago. Should the documentation be updated? Is it true for all computers?

I have seen these results running on macOS 10.15.7, Processing 4.01, and the latest Sound library 2.3.1.

The range of values of the samples should indeed be documented somewhere in the reference (at least for advanced users), thanks for reporting!
