The Vocoder was once invented as a method of reducing the bandwidth of a vocal signal, as a way to reduce cost for expensive transatlantic copper cables, however, artists through the 70’s, 80’s, and even today use vocoders as a way of processing instruments and vocals. This distinctive technique creates a uniquely, sometimes robotic sounds, and is an effective route to bring science fiction to life.

The child patch is really quite simple;

Inside of the parent function, I created harmonics within the vocoder, by passing a major fifth chord into the algorithm. This makes the timbre of the vocoder flexible, allowing for a large range of sounds.

Here is an example of the vocoder, with tweaks to the parameters as time goes on.
