Audio is the sound half of Voro. You patch it like any other TouchDesigner family: operators, wires, parameters. The difference is underneath. The whole audio network compiles into one engine plan that runs on its own worker at 48 kHz, independent of the frame loop, and audio, spectrum, note, chord, control and timeline streams move through it as typed wires.

Start with First patches for four shapes that work, and Engine and streams for what the wires carry.
