Bach Prelude in C major Diffusion Analysis Visualization 1

Using 12 mel frequency cepstral coefficients to represent each 50 milisecond frames of audio. Calculated self-similarity using windows of 4 frames. The first three subplots display a 3d scatter plot of the complete data set, in which display color is proportional to height to make it easier to perceive depth. The final subplot shows a convex hull surface fit to the data. Three views are shown, a "front" view in the lop left subplot, a "top" view in the top right subplot, a standard 3d view in the third subplot, and a 3d view in the last two subplots. As the audio plays, the black triangle shows the current data point and the red triangles show the last 2 data points. Speed is 20 FPS.
