I have always been drawn to the idea of sound having a physical presence, something you do not just hear but actually move through. In this experiment I wanted to visualize that feeling, translating audio data into a space that shifts and reacts in real time. Using TouchDesigner, I fed audio through CHOPs and converted that signal into visual motion, letting the frequencies dictate the shape, speed, and intensity of what you see on screen. The result, in my view, came out really well and captured exactly that sense of traveling through a living, breathing sound environment.
For anyone starting out, the core idea is simpler than it looks. You take an audio signal, bring it into TouchDesigner using an Audio Device In CHOP, and then use an Analyze CHOP to extract values like volume or frequency. Those values become numbers that drive parameters in your TOPs, things like displacement, color, or blur amount. Essentially you are mapping sound to visuals, so when the audio hits hard the visuals react, and when it gets quiet everything settles. Start small, connect one CHOP output to one parameter and just watch how it responds. Once that clicks, you can keep layering and the whole network starts to feel alive.
How I did that, you can see through this post:
