Morphing : Phase Vocoder based morphing module — Cecilia 5.4.1 documentation

# Morphing : Phase Vocoder based morphing module

## Description

This module performs spectral morphing between two phase vocoder analysis.

According to Morphing Index, the amplitudes from two PV analysis are interpolated linearly while the frequencies are interpolated exponentially.

## Sliders

> Morphing Index :

>   Morphing index between the two sources

> Dry / Wet :

>   Mix between the original signal and the morphed signal

## Graph Only

> Overall Amplitude :

>   The amplitude curve applied on the total duration of the performance

## 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
