Reed Evan Rosenberg, b. 1986, works with sound, code, lighting and language, to create work that synthesizes his interests in noise, dynamical systems, science fiction, sublimated violence, puckishness and utopia-in-general.

30 April 2012 // Clip of live diffusion of self-similar system for Chirikov Standard Map chaotic oscillators and consumer-grade DJ LED bars.

Captured on Droid by Ian M. Fraser.

The chaotic differential equation known simply as the Standard Map "describes a universal, generic behavior of area-preserving maps when integrable islands of stability are surrounded by a chaotic component."

Systems reducible to the standard map include:

fast crossing of nonlinear resonance

particle dynamics in accelerators

comet dynamics in solar system with a rather similar map for the comet Halley

KEROAÄN live diffusion @ Str8 Cavin, Baltimore // Jan 12, 2012

KEROAÄN is a musical artificial intelligence developed by FRASER/ROSENBERG that performs by implementing XENAKIS'S Dynamic Stochastic Synthesis. This non-standard synthesis is played in real time by the KEROAÄN program. Pushing and pulling between sections of hard noise, singing glissandos, jagged melodic scribble and other sonic curiosities, the program liberates the computer from its position as a mere tool of hyper-productivity and transports the machine into a state of creative and performative being. Operatic in scope, a live diffusion of KEROAÄN features lasers, strobe lighting, and fog synched to both audible and structural qualities of the music as an infinitely morphing chorus of digital voices croon, cry, scream and everything in between.

The Trajectory Toward Which All Other Trajectories Converge by Ian M. Fraser & Reed Evan Rosenberg

from Lateral Addition #1, a bi-yearly web-based audio journal:

"To understand the trajectories of the stars through a galaxy, Michel Hénon computed the intersections of an orbit with a plane. The resulting patterns depended on the system's total energy. The points from a stable orbit gradually produced a continuous, connected curve. Other energy levels, however, produced complicated mixtures of stability and chaos, represented by regions of scattered points.

The nested detail, lines within lines, can be seen in final form in a series of pictures with progressively greater magnification. But the eerie effect of the strange attractor can be appreciated another way when the shape emerges in time, point by point. It appears like a ghost out of the mist. New points scatter so randomly across the screen that it seems incredible that any structure is there, let alone a structure so intricate and fine. Any two consecutive points are arbitrarily far apart, just like any two points initially nearby in a turbulent flow. Given any number of points, it is impossible to guess where the next will appear—except, of course, that it will be somewhere on the attractor.

The points wander so randomly, the pattern appears so ethereally, that it is hard to remember that the shape is an attractor. It is not just any trajectory of a dynamical system. It is the trajectory toward which all other trajectories converge. That is why the choice of starting conditions does not matter. As long as the starting point lies somewhere near the attractor, the next few points will converge to the attractor with great rapidity."

From Chaos: Making A New Science by James Gleick (pgs. 148-150)

The track is a collection of études whose content is entirely derived from sonification of the Hénon Map and a sound file of the Chaos: Making A New Science AAX format audiobook interpreted as raw audio data.

Realized in real time without any human interference, each étude is the diffusion of a single variation of a compact patch coded by Fraser & Rosenberg in Supercollider in which the chaotic sonifications modulate various parameters regulating the playback of the raw data sound file. The études were sequenced in Audacity, each separated by a period of silence. All software utilized in the piece is free and open source.
