# 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
