is enabled, fidelity can be affected. For example,
time expansion as a result of Time Correction
when lowering pitch can cause the audio to
sound granulated.
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-
quire smaller crossfades. Long crossfade times
may over-smooth a signal and its transients.
This is may not be desirable on drums and other
material with sharp transients.
Use the Crossfade slider to adjust and optimize
crossfade times. For audio material with sharper
attack transients, use smaller crossfade times.
For audio material with softer attack transients,
use longer crossfade times.
Min Pitch Sets the lowest pitch used in the plug-
in’s Pitch Shift processing. The control has a
range of 40 Hz to 1000 Hz. Use it to focus the
Pitch Shift process according to the audio’s spec-
tral shape.
Use lower values when processing bass guitar or
audio material with a low frequency range. Use
higher values when processing higher frequency
audio material.
Accuracy Prioritizes the processing resources al-
located to audio quality (Sound) or timing
(Rhythm). Set the slider toward Sound for better
audio quality and fewer audio artifacts. Set the
slider toward Rhythm for a more consistent
tempo.
Reference Pitch Activates a sine wave-based
pitch generator that you can use as an audible
reference when pitch-shifting audio material.
This feature has the following controls:
Note Adjusts the frequency of the reference tone
in semitones (half steps).
Detune Provides finer adjustment of the fre-
quency of the reference tone in cents (100ths of
a semitone).
Gain Adjusts the volume of the reference tone
in dB.
