How Auto-Tune 3 corrects pitch
Auto-Tune 3 provides two separate and distinct ways to approach pitch
correction: Automatic Mode and Graphical Mode. The basic functionality
of each is described below.
Automatic Mode
Auto-Tune 3’s Automatic Mode works by continuously tracking the pitch
of an input sound and comparing it to a user-defined scale. The scale tone
closest to the input is continuously identified. If the input pitch exactly
matches the scale tone, no correction is applied. If the input pitch varies
from the desired scale tone, an output pitch is generated which is closer to
the scale tone than the input pitch. (The exact amount of correction is
controlled by the Retune Speed parameter, described below and in Chap-
ter 3.)
