120 Chapter 10 Pitch
 Vocals retains the intonation of the original with no change. Hence Vocals is well-
suited for any signals that are inherently harmonic or melodious, such as string
pads.
 Speech provides a compromise between the two by attempting to retain both the
rhythmic and harmonic aspects of the signal. This is suitable for complex signals
such as spoken-word recordings, rap music, and other hybrid signals such as
rhythm guitar.
 Mix slider and field: Sets the amount of the processed signal mixed with the original
signal.
 Timing pop-up menu (extended parameters): Sets whether the timing follows the
selected preset (Preset), creates a new preset by analyzing the incoming signal (auto),
or uses the settings of the Delay, Crossfade, and Stereo Link parameters, described
below (manual).
The following three parameters are active only when manual is chosen in the Timing
pop-up menu.
 Delay slider and field: Sets the amount of delay applied to the input signal. The
deeper the frequencies of the input signal, the higher (longer) a delay time you
should set—in order to effectively pitch shift the signal.
 Crossfade slider and field: Sets the amount of crossfading between the two
pointers—used by the Pitch Shifter to analyze the input signal.
 Stereo Link pop-up menu: Choose Inv. to invert the stereo channel’s signals, with the
processing for the right channel occurring on the left, and vice versa. Choosing
Normal produces no change to the signal.
Using Pitch Shifter II
Set the amount of transposition (pitch shift) with the Semi Tones parameter, then set
the amount of detuning with the Cents parameter. Use one of the three presets
(Drums, Vocals, or Speech) depending on the material you are working with. For other
types of material, you can try each of the presets (starting with Speech), compare the
results, and use the one that best suits your material. While you are auditioning and
comparing different settings, it’s often a good idea to temporarily set the Mix
parameter to 100% to hear the maximum effect of the processing. Keep in mind that
Pitch Shifter II artifacts are much harder to hear with Mix set to a smaller percentage.
In the Pitch Shifter II’s Controls view, you can create your own presets using the Delay
and Crossfade parameters. These parameters are only effective when you select the
Manual option in the Timing menu. You can also select the Auto option here—the
Pitch Shifter will then automatically create presets by analyzing the incoming signal.
The Stereo Link parameter allows you to invert the stereo channel’s signals, with
processing for the right channel occurring on the left and vice versa.
