# SpectralFilter : Phase Vocoder based filter

## Description

This module filters frequency components of a phase vocoder analysed sound according to the shape drawn in the grapher function.

## Sliders

> Dry / Wet :

>   Mix between the original signal and the processed signal

## Graph Only

> Spectral Filter :

>   Shape of the filter (amplitude of analysis bins)

> 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
