SpectralGate : Spectral gate (Phase Vocoder) — Cecilia 5.4.1 documentation

# SpectralGate : Spectral gate (Phase Vocoder)

## Description

For each frequency band of a phase vocoder analysis, if the amplitude of the bin falls below a given threshold, it is attenuated according to the Gate Attenuation parameter.

## Sliders

> Gate Threshold :

>   dB value at which the gate becomes active

> Gate Attenuation :

>   Gain in dB of the gated 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
