LIES (distance/incidence) is a human-machine interaction improvised performance implementing complex dynamical systems based on analog and digital audio feedback networks. The digital network consists of sound transformation 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 consists of microphones and loudspeakers, and when enough amplification is provided, self-oscillation occurs; the digital network enters an operating state, and the two interdependent and interacting networks act as a single sound generator. No randomness or automated processes are implemented in the system, yet dynamical and unpredictable behaviours 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 and the angle of incidence with which they capture sounds, 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.
