This is an experiment in using TouchDesigner for everything, audio and video. Although TD has some cool audio features, I wouldn’t necessarily recommend it for this purpose after trying it. The two biggest reasons for this are the CPU requirements, and the fact that there are generally better, easily-available tools for the audio side of things.
That said, it was fun to create something where the video reacts not only to the audio itself, but also some of the control signals being used in the audio synthesis.
