+module: p5.sound
+submodule: p5.sound
+file: lib/addons/p5.sound.js
+description: |
+  <p>Determines whether the results of Amplitude.process() will be
+  Normalized. To normalize, Amplitude finds the difference the
+  loudest reading it has processed and the maximum amplitude of
+  1.0. Amplitude adds this difference to all values to produce
+  results that will reliably map between 0.0 and 1.0. However,
+  if a louder moment occurs, the amount that Normalize adds to
+  all the values will change. Accepts an optional boolean parameter
+  (true or false). Normalizing is off by default.</p>
