of repetitions of the delayed signal. You can use
it to produce effects that spiral up or down in
pitch, with each successive echo shifted in
pitch.
Coarse Adjusts the pitch of a signal in semitones
over a two octave range. Pitch changes are indi-
cated both in the Semitones field and in the Mu-
sical Staff Relative section below this slider. Us-
ing the –8va and +8va buttons in conjunction
with the Coarse slider provides a full 4-octave
range of adjustment.
–8va and +8va Buttons Clicking the –8va button
adjusts pitch down one octave from the current
setting of the coarse and fine pitch controls.
Clicking the +8va button adjusts pitch up one
octave from the current setting of the coarse and
fine pitch controls.
Relative Pitch Entry (Musical Staff)
Clicking on any note on this musical staff se-
lects a relative pitch transposition value that
will be applied to an audio signal. If Middle C is
illuminated, it indicates that no pitch transposi-
tion has been selected. If a pitch transposition is
selected, the note interval corresponding to the
selected transposition value is indicated in yel-
low. Alt-clicking (Windows) or Option-clicking
(Macintosh) on the staff will set the coarse pitch
change value to zero.
Fine Controls the pitch of a signal in cents (hun-
dredths of a semitone) over a 100 cent range.
The range of this slider is –49 to +50 cents. Pre-
cise Pitch change values are indicated in the
Cents field. The flat, natural, and sharp signs be-
low this slider indicate deviation from the near-
est semitone.
Ratio Indicates the ratio of transposition be-
tween the original pitch and the selected trans-
position value.
Crossfade Adjusts crossfade length in millisec-
onds to optimize performance of the Pitch plug-
in according to the type of audio material you
are processing. The Pitch plug-in performs pitch
transposition by replicating or subtracting por-
tions of audio material and very quickly cross-
fading between these alterations in the wave-
form of the audio material.
Crossfade length affects the amount of smooth-
ing performed on audio material to prevent au-
dio artifacts such as clicks from occurring as the
audio is looped to generate the pitch shift.
In general, small, narrow-range pitch shifts re-
quire longer crossfades and large shifts require
smaller ones. The disadvantage of a long cross-
fade time is that it will smooth the signal, in-
cluding any transients. While this is sometimes
desirable for audio material such as vocals, it is
not appropriate for material with sharp tran-
sients such as drums or percussion.
The default setting for this control is Auto. At
this setting, crossfade times are set automati-
cally, according to the settings of the Coarse and
Fine pitch controls. The Auto setting is appro-
priate for most applications. However, you can
manually adjust and optimize crossfade times
using the Crossfade slider if necessary. For audio
material with sharper attack transients, use
shorter crossfade times. For audio material with
softer attack transients, use longer crossfade
times.
