LIES (distance/incidence)

LIES (distance/incidence) is a human-machine interaction improvised performance implementing complex dynamical systems based on analog and digital nonlinear feedback networks. The digital network consists of sound processing units where feedback coefficients are below the self-oscillating threshold, and where each unit has a different sensitivity to the intensity and spectral profile of input signals. The analog feedback network, englobing the digital network, consists of microphones and loudspeakers. When enough amplification is provided, self-oscillation occurs and the digital network enters an operating state: the two interdependent and interacting networks act as a single sound generator. No randomness or automated processes are implemented in the system, yet short- and long-term dynamical and unpredictable behaviors will be exhibited, where sound affects itself and autonomously evolves through time. The performer interacts with the system through the microphones by varying the distance from the loudspeakers (the feedback coefficient) and the angle of incidence with which they capture sounds (filtering), thus altering the relation the system has to itself, and exploring the anti/resonances of a 3D environment which is constantly mediating the whole process.

CUBE Lecture 14.05.2013, 19:00 Uhr

Complex dynamical feedback systems

In this lecture Dario Sanfilippo will shortly introduce feedback systems by describing their characteristics and cybernetic principles, then he will relate such systems within the framework of emergence and complexity. Concepts like nonlinearity, circular causality, interaction, self-dis/organization and chaos will be discussed, as well as synergy and organicity in the sonic domain. Moreover, he will describe some of the processes he has implemented in his sonic systems, such as recursive asynchronous granulation and recursive nonlinear distortion. Finally, he will also talk about the properties of these systems from a musical perspective, focusing on aspects related to the aesthetics of the machine, autonomous systems, identity and the subversion of technology.
