Chapter 22: Pitch Shift
Pitch Shift is an AudioSuite plug-in that pro-
vides pitch-based processing.
The Pitch Shift plug-in adjusts the pitch of any
source audio file with or without a change in its
duration. This is a very powerful function that
transposes audio a full octave up or down in
pitch with or without altering playback speed.
Pitch Shift Controls
This Pitch Shift plug-in provides the following
controls:
Gain Adjusts input level, in 10ths of a dB. Drag-
ging the slider to the right increases gain, drag-
ging to the left decreases gain.
Coarse and Fine Adjusts amount of pitch shift.
The Coarse slider transposes in semitones (half
steps). The Fine slider transposes in cents (hun-
dredths of a semitone).
Ratio Adjusts the amount of transposition
(pitch change). Moving the slider to the right
raises the pitch of the processed file, while mov-
ing the slider to the left decreases its pitch.
Crossfade Use this to manually adjust crossfade
length in milliseconds to optimize performance
of the Pitch Shift plug-in according to the type
of audio material you are processing. This plug-
in achieves pitch transposition by processing
very small portions of the selected audio mate-
rial and very quickly crossfading between these
alterations in the waveform of the audio mate-
rial.
Crossfade length affects the amount of smooth-
ing performed on audio material. This prevents
audio artifacts such as clicks from occurring. In
general, smaller pitch transpositions require
longer crossfades; wider pitch transpositions re-
