Bruno Friedmann, algorithmic composition with 4 attractors (Lorenz, Thomas, Rössler, Lu Chen), 2020, for 8 loudspeakers; 13 min
The trajectory of an attractor, described by mathematical differential equations, shows fascinating movements and time dependencies. The Lorenz attractor for example develops the famous 3-dimensional wings of a butterfly, seen from a certain point in space.
The movements of attractor’s trajectories is never the same but the forms of the tracks might be similar. This so called fractal behaviour can evolve beautiful 3-dimensional bodies.
Transforming the attractor’s behaviour into the audible domain, the resulting sound and music should reflect it in a characteristic way. Every attractor is metamorphosed into a stereo track with changing stereo width, moving around in space. L’océan du son positions the listener somewhere inside the trajectories› traces or between the four attractor spaces which also moves and respires slowly.
Even the sonogramme of the binaural mixdown shows the fractal movements of the frequency changes:
The trajectories fills up the 3-dimensional space successively, the rhythm of the moving trajectories breaths like the moving waves of an ocean. Different ocean currents create interferences, the waves mingles, the space is filled up with movements and turns.
