"Audio Nodes: Live Sound, Living Geometry" by Cem Özcan at Blender Conference 2026

Audio Nodes is a Blender add-on that turns sound into a live creative input for Blender. Instead of treating audio as data baked to the timeline, it lets artists build sound-reactive systems with familiar node workflows using sequencers, samplers, audio filters, MIDI controls, FFT analysis, and real-time links to geometry nodes, shader nodes, or any Blender property that is driver-friendly.This workshop shows how audio can become a first-class driver inside Blender, enabling scenes that pulse, deform, glow, and perform in direct response to live sound.
