Chapter 21: Pitch
Pitch is a pitch-shifting plug-in that is available
in TDM and AudioSuite formats.
The Pitch plug-in is designed for a variety of au-
dio production applications ranging from pitch
correction of musical material to sound design.
Pitch processing uses the technique of varying
sample playback rate to achieve pitch transposi-
tion. Because changing audio sample playback
rate results in the digital equivalent of vari-
speeding with tape, this is an unsatisfactory
method since it changes the overall duration of
the material.
Pitch transposition with the Pitch plug-in in-
volves a much more complex technique: digi-
tally adding or subtracting portions of the audio
waveform itself, while using de-glitching cross-
fades to minimize undesirable artifacts. The re-
sult is a processed signal that is transposed in
pitch, but still retains the same overall length as
the original, unprocessed signal.
Pitch Controls
The Pitch plug-in provides the following con-
trols:
Input Level This control attenuates the input
level of the Pitch plug-in to help prevent inter-
nal clipping.
Signal Present Indicator LED This LED indicates
the presence of an input signal.
The Pitch plug-in was formerly called
DPP-1. It is fully compatible with all set-
tings and presets created for DPP-1.
