/* Here is where the algorithm determining

* 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.
