Pitch Shift
The Pitch Shift effect shifts the frequency spectrum of the input signal. It can be used to disguise a person's voice, or make the voice sound like that of the "chipmunks", through to "Darth Vader". It is also used to create harmony in lead passages, although it is an "unintelligent" harmonizer.
It's possible to select the necessary preset from the dropdown list clicking the Load preset button or set a custom Rate value.
