Pitch Shifter
Pitch Shifter overview
Pitch Shifter provides a simple way to combine a pitch-shifted version of the signal with the
original signal. Use pitch shifting to achieve the best results.
•
Semi Tones slider and eld: Drag to set the pitch shift value in semitones.
•
Cents slider and eld: Drag to control detuning of the pitch shift value in cents (1/100th of a
semitone).
•
Drums, Speech, and Vocals buttons: Set one of three optimized algorithms for common types of
audio material. Choose from:
•
Drums: Maintains the groove (rhythmic feel) of the source signal.
•
Speech: Provides a balance between 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.
•
Vocals: Retains the intonation of the source, making it well-suited for signals that are
inherently harmonic or melodious, such as string pads.
•
Mix slider and eld: Drag to set the balance between the eect and original signals.
•
Timing pop-up menu (Extended Parameters area): Choose how timing is derived:
•
Preset: Follows the selected algorithm.
•
Auto: Analyzes incoming audio.
•
Manual: Uses the settings of the Delay, Crossfade, and Stereo Link parameters.
Note: The following three parameters are active only when Manual is chosen from the Timing
pop-up menu.
•
Delay slider and eld (Extended Parameters area): Drag to set the amount of delay applied to the
input signal. The lower the frequencies of the input signal, the higher (longer) a delay time you
should set—to eectively pitch shift the signal.
•
Crossfade slider and eld (Extended Parameters area): Drag to set the range (expressed as a
percentage of the original signal) used to analyze the input signal.
•
Stereo Link buttons (Extended Parameters area): Click Inv. to invert the stereo channel’s signals,
with processing for the right channel occurring on the left, and vice versa. Click Normal to
leave the signal as it is.
