Today's sketch is a play on the random shape clusters that I seem to be gravitating towards. I used the spectral feature extraction from Day 5 so not all of the code is posted below. You can go to that post and rip the features if you like.
This sketch uses a more coherent model instead of randomness. There are 20 3D boxes in the sketch that have their colour and placement changed based upon the sound coming into the sketch. It is reactive but a little too literal. I think I will try to make some mappings in the future that can take spectral centroids and do something meaningful visually. Sounds like a research project!
