Pitch
(TDM Only)
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
Input Level Attenuates the input level of the
Pitch plug-in to help prevent internal clipping.
Signal Present Indicator LED Indicates the pres-
ence of an input signal.
Clip Indicator Indicates whether clipping has oc-
curred on output. It is a clip-hold indicator. If
clipping occurs at any time, the clip light will re-
main on. To clear the Clip indicator, click it.
Long delay times and high feedback times in-
crease the likelihood of clipping.
The Pitch plug-in was formerly called
DPP-1. It is fully compatible with all set-
tings and presets created for DPP-1.
