Harpex is a process that deals with spatial audio. In the GUI, there's a nice audio visualizer and I would like to make something similar or inspired by it with Vuo. This video gives an idea (the fun starts at 40 secs): http://harpex.net/demovideo.mp4
So a "sound" is visualized, more or less, by a cloudy dot: the audio amplitude is represented the size of the cloudy dot and the audio frequency by the color of the cloudy dot. The visualization is also spatially aware. If I was to make a stereo version, the cloudy dot would follow the sound: a left only sound would be on the left of the screen, a right sound on the right, and a sound with equal amplitude in both channels would be in the center.
Does Vuo have the right nodes to build something similar? If so, what would be these nodes?
