Pitch shifting audio events

A pitch shift is a way to raise or lower the pitch of an audio event. The semitone range is -24 to 24. Twelve semitones equal one octave, so you may increase or decrease the pitch of an event within a two-octave range. Within each semitone is a finer pitch adjustment called cents. There are one hundred cents in one semitone.
