VOC

A channel vocoder. mod (a voice, or anything with a moving spectrum) shapes car (a synth — a saw, a pad, noise) so the carrier TALKS: the robot-voice / talkbox effect. It splits both into 16 bands, follows the modulator's level per band, and gains the carrier's bands to match. formant shifts the spectrum up or down (voice size); attack/release set how crisp or smeared it is. For a classic vocoder patch a sampled voice (SMPL) into mod and a bright saw into car.

The VOC card as vimsynth draws it: its title bar, 4 knobs, 2 inputs down the left edge and 1 outputs down the right
VOC on an empty rack — 32×12 cells, knobs at their defaults. Press a in the app and pick VOC to get this card.

inputs

Down the left edge of the card, top to bottom.

modaudio
The modulator — a voice, or anything whose spectrum should shape the carrier.
caraudio
The carrier — a synth, a saw, noise. It comes out wearing the modulator's spectrum.

outputs

Down the right edge, in the same order.

outaudio
The carrier, shaped by the modulator's spectrum — the talking synth.

knobs

Left to right across the face — the dials in the picture.

formant-1 … 1= 0
Formant shift. 0 is voice-for-voice; positive lifts the spectrum (smaller, brighter), negative drops it (bigger, darker) — the size of the mouth, independent of pitch.
attack0 … 1= 0.15
Follower attack, fast at 0 to slow at 1. Fast keeps consonants crisp.
release0 … 1= 0.3
Follower release, fast at 0 to slow at 1. Slow smears the bands into a pad.
mix0 … 1= 1
Vocoded carrier against the raw carrier — how much of the effect.
