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.
