Brown

In my MAT 201B course, “Programming with Media Data,” I’ve developed an audio/visual representation of different molecular random walks, including a loose model of Brownian motion. The fluctuations in the spatial displacements are mapped to color (in terms of HSV) and pitch (in terms of frequency). The user can interact with the simulation, discretely or continuously varying the temperature to affect the magnitude of the displacements. I’ve created two other stochastic processes in addition to the Brownian motion and included a mode which cycles rapidly between the three random walks, essentially producing a ‘random walk between random walks.’ I also programmed a short piece which illustrates the various aspects of my project in action. You can see a video screen capture of it below.

I recently finished composing a slightly longer piece, “Crackle,” based on similar themes to “Snap.” In “Crackle,” I’ve used only one sample of myself snapping my fingers in an homage/satire of Steve Reich’s “Clapping Music.” Using Pro Tools again, the sample is developed in a variety of ways, but principally with time-distortion, reverb, and panning.
