  	/* Here is where the algorithm determining
  	 * how much to shift each pitch will be.
  	 * there are multiple ways we can implement this...
  	 *
  	 * We can either shift each pitch to the nearest semitone or
  	 * shift it in the context of a certain key. The problem with
  	 * shifting it to the nearest semitone is that the output would
  	 * most likely be atonal, which is not likely to be desirable for
  	 * someone needing autotune. If we shift in the context of a
  	 * certain key, then we can match it to some predetermined
  	 * key inputted by the user or by the first (or first several) notes
  	 * of the inputted file. We could determine what semitone to
  	 * match to by comparing it to an array of notes (their Hz values)
  	 * in that key and finding the closest one.
