Pitch Shift

GOALS:
- Fix out of tune tracks that can’t be re-recorded correctly.
- Fit bits of a crowded mix together with the help of a pitch-based spreader, thickener, or layering effect.
- Feature tracks with obvious new pitch qualities, composing new musical parts, and imparting a new shape to any melody or chord sequence.
GEAR:
- Extraordinary signal processing sophistication is accompanied by complex, and rarely intuitive user interfaces.
- Musical use of pitch correction tools requires mastery of the parameters and practice with the processor.
- Listen carefully. Pitch perfection is not always the best answer. Learn to expect unexpected artifacts.

Spreader

Pitch Shift (just a few cents) + Delay (just a few milliseconds) are the basis of a common mix move casually known as a signal ‘spreader.’ Let’s do it.
Thickener

More Pitch Shift + longer Delay creates regenerative, uncorrelated energy that can add a kind of ‘thickness’ to the timbre of the track. Let’s do it.
The Pitch Shift-ography
Have a listen to some great recordings with some clever Pitch Shift FX.
And, of course, the first digital pitch shifter was invented by the good folks at Eventide.
