CrossSynth2 : Phase Vocoder based cross synthesis module — Cecilia 5.4.1 documentation

# CrossSynth2 : Phase Vocoder based cross synthesis module

## Description

Performs cross-synthesis between two phase vocoder streaming objects.

The amplitudes from Source Exciter and Spectral Envelope, scaled by Crossing Index, are applied to the frequencies of Source Exciter.

## Sliders

> Crossing Index :

>   Morphing index between the two source’s magnitudes

> Exc Pre Filter Freq :

>   Frequency of the pre-FFT filter

> Exc Pre Filter Q :

>   Q of the pre-FFT filter

> Dry / Wet :

>   Mix between the original signal and the processed signal

## Graph Only

> Overall Amplitude :

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

## Popups & Toggles

> Exc Pre Filter Type :

>   Type of the pre-FFT filter

> 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
