BinModulator : Frequency independent amplitude and frequency modulations — Cecilia 5.4.1 documentation

# BinModulator : Frequency independent amplitude and frequency modulations

## Description

This module modulates both the amplitude and the frequency of each bin from a phase vocoder analysis with an independent oscillator. Power series are used to compute modulating oscillator frequencies.

## Sliders

> AM Base Freq :

>   Base amplitude modulation frequency, in Hertz.

> AM Spread :

>   Spreading factor for AM oscillator frequencies. 0 means every oscillator has the same frequency.

> FM Base Freq :

>   Base frequency modulation frequency, in Hertz.

> FM Spread :

>   Spreading factor for FM oscillator frequencies. 0 means every oscillator has the same frequency.

> FM Depth :

>   Amplitude of the modulating oscillators.

> Dry / Wet :

>   Mix between the original signal and the delayed signals

## Graph Only

> Overall Amplitude :

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

## Popups & Toggles

> Reset :

>   On mouse down, this button reset the phase of all bin’s oscillators to 0.

> Routing :

>   Path of the sound

> AM Shape :

>   Waveform of the amplitude modulators. Possible shapes are: Sine, Sawtooth, Ramp, Square, Triangle, Brown Noise, Pink Noise, White Noise

> FM Shape :

>   Waveform of the frequency modulators. Possible shapes are: Sine, Sawtooth, Ramp, Square, Triangle, Brown Noise, Pink Noise, White Noise

> 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
