Pitch Shifter
Logic Pro Pitch Shifter overview
Pitch Shifter provides a simple way to combine a pitch-shifted version of the signal with
the original signal. See Use Logic Pro Pitch Shifter.
Pitch Shifter parameters
• Semi Tones knob and field: Set the pitch shift value in semitones.
• Cents knob and field: Control detuning of the pitch shift value in cents (1/100th of
a semitone).
• Mix knob and field: Set the balance between the effect and original signals.
• Latency Comp button: Turn on to compensate for delays that may be introduced by
some algorithms with particular types of source material.
• Stereo Link buttons: Normal retains the source stereo signals. Invert swaps
(inverts) stereo channel signals, with right channel processing occurring on
the left, and vice versa.
• Timing pop-up menu: Choose an algorithm to determine how timing is derived.
• 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, and
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.
• Manual: Uses the settings of the Delay, Crossfade, and Stereo Link parameters.
• Pitch Tracking: Follows the pitch of incoming audio material.
Note: The following parameters are active only when Manual is chosen from the Timing
pop-up menu.
• Delay slider and field: Set the amount of delay applied to the input signal. The lower
the frequencies of the input signal, the higher (longer) a delay time is required—to
effectively pitch shift the signal.
• Crossfade slider and field: Set the range (shown as a percentage of the original signal)
used to analyze the input signal.
