Shifter : Phase Vocoder based frequency shifters — Cecilia 5.4.1 documentation

# Shifter : Phase Vocoder based frequency shifters

## Description

This module implements two voices that linearly moves the analysis bins by the amount, in Hertz, specified by the the Shift 1 and Shift 2 parameters.

## Sliders

> Shift 1 :

>   Shifting, in Hertz, of the first voice

> Shift 2 :

>   Shifting, in Hertz, of the second voice

> Dry / Wet :

>   Mix between the original signal and the delayed signals

## Popups & Toggles

> FFT Size :

>   Size, in samples, of the FFT

> FFT Envelope :

>   Windowing shape of the FFT

> FFT Overlaps :

>   Number of FFT overlaping analysis

> Polyphony Voices :

>   Number of voices played simultaneously (polyphony), only available at initialization time

> Polyphony Spread :

>   Pitch variation between voices (chorus), only available at initialization time
