Audio Plug-Ins Guide140
For highly percussive material, lower the Sensi-
tivity for better transient detection, especially
with the Rhythmic audio setting. For less per-
cussive material, a higher setting can yield bet-
ter results. Experiment with this control, espe-
cially when shifting drums and percussive
tracks, to achieve the best results.
Window
Sets the analysis window size. You can adjust the
Window from 10.0 milliseconds to 100.0 milli-
seconds. Adjust the Window control or click the
Window field and type the desired value. Win-
dow is only available when Monophonic is se-
lected as the Audio Type.
Try larger window sizes for low frequency
sounds or sounds that do not have many tran-
sients. Try smaller window sizes for tuned
drums and percussion. However, the default of
25 milliseconds should work well for most mate-
rial.
X-Form Pitch Section Controls
The Pitch section provides controls for pitch
shifting the selected audio. Use the Pitch control
to transpose the pitch from as much as –36.00
semitones (–3 octaves) to +36.00 semitones (+3
octaves), with fine resolution in cents, depend-
ing on which Range button is enabled (2x, 4x, or
8x). X-Form also lets you transpose the formant
shape independently of the fundamental fre-
quency.
Transpose
Displays the transposition amount in semitones.
You can transpose pitch by as much as –36.00
semitones (–3 octaves) to +24.00 semitones (+3
octaves), with fine resolution in cents, depend-
ing on which Range button is enabled. Adjust
the Pitch control or click the Transpose field
and type the desired value. The default value is
0.00 semitones, or no pitch shift.
Shift
Displays the pitch shift amount as a percentage.
You can shift pitch by as much as 12.50% (–3 oc-
taves) to 800.00% (+3 octaves) depending on
which Range button is enabled (2x, 4x, or 8x).
Adjust the Pitch control or click the Shift field
and type the desired value. The default value is
100%, or no pitch shift.
Formant
Audio with a fundamental pitch has an overtone
series, or set of higher harmonics. The strength
of these higher harmonics creates a formant
shape, which is apparent if viewed using a spec-
trum analyzer. The overtone series, or harmon-
ics, have the same spacing related to the pitch
and have the same general shape regardless of
what the fundamental pitch is. It is this formant
shape that gives the audio its overall character-
istic sound or timbre. When pitch shifting au-
dio, the formant shape is shifted with the rest of
the material, which can result in an unnatural
sound. Keeping this shape constant is critical to
formant correct pitch shifting and achieving a
natural sounding result.
The Pitch section of X-Form lets you pitch shift
the formants of the selected audio indepen-
dently of the fundamental frequency. This is
useful for achieving formant correct pitch shift-
