How do Voice/Audio Changer's Work?

The vast majority of "voice changers" shift the pitch-sensitive fundamental waves of the users voice via a microprocessor and offer various pitch shift options. "Low end" models offer less pitch options and use a less effective microprocessor than "high end" models.

Since the human voice only has one element, pitch, there are limitations as to how much change can be made without resulting in an "unnatural" or "digital" sounding voice. High end models use additional electronic circuits to offset or buffer the unnatural sounds as well as more efficient pitch shifting microprocessors . Lower end models are generally for use as a novelty item for practical jokes or for kids. (Kids love them as gifts) If you have a serious application, consider only the "Pro" models.
