End of jam report: I added a system for mixing all input tracks into a master track to perform additional analysis & visualization on the combined track. I added a pretty typical visualization for the mixed track that also serves to visually "frame" the video a little bit. I tuned up the effects to make them just right for the final videos. Finally I added command line parameterization so I can reuse the program without having to edit the parameters and generate noisy git commits.
