UltimateGrainer : A state-of-the-art granulation processing module — Cecilia 5.4.1 documentation

# UltimateGrainer : A state-of-the-art granulation processing module

## Description

This module offers more controls than the classic granulation module. Useful to generate clouds, to stretch a sound without changing the pitch or to transpose without changing the duration. It features a grain filter with control over type, frequency and Q for each grain.

Density per Second * Grain Duration defines the overall overlaps.

## Sliders

> Density per Second :

>   How many grains to play per second

> Transpose :

>   Overall transposition, in cents, of the grains

> Grain Position :

>   Soundfile index

> Grain Duration :

>   Duration of each grain, in seconds

> Start Time Deviation :

>   Maximum deviation of the starting time of the grain

> Filter Freq :

>   Filter cutoff or center frequency, chosen at the beginning of the grain

> Filter Q :

>   Filter Q, chosen at the beginning of the grain

> Panning Random :

>   Random added to the panning of each grain

> Density Random :

>   Jitter applied to the density per second

> Pitch Random :

>   Jitter applied on the pitch of the grains

> Position Random :

>   Jitter applied on the soundfile index

> Duration Random :

>   Jitter applied to the grain duration

> Filter Freq Random :

>   Jitter applied to the grain’s filter cutoff or center frequency

> Filter Q Random :

>   Jitter applied to the grain’s filter Q

## Graph Only

> Overall Amplitude :

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

> Grain Envelope :

>   Emplitude envelope of the grains

## Popups & Toggles

> Balance :

>   Compression mode. Off, balanced with a fixed signal or balanced with the input source.

> Filter Type :

>   Type of the grain’s filter (Lowpass, Highpass, Bandpass, Bandstop, Allpass)

> Filter Freq Ratio :

>   List ratios used to randomize grain’s filter frequency

> Discreet Transpo :

>   List of pitch ratios

> 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
