Three rotating acoustic parabolic mirrors reflect sound/light in the room and explore possibilities of articulating the sound spatial qualities with this experimental technique. Objects remind radar predecessors: acoustic mirrors built on the coast of southern England that were planned to use for detecting arriving fighters during WW2. Invention of radar makes this technology obsolete. Installation is refreshing this „war technology“ in a context of spatial audio research and sound art and by this act is also questioning the role of technology in a society and the development of its the goals and transformation of its usage over time.

Installation Perplex deals with the theory of information and (dis)interpretation of the signal sources by multiple reflections/distortions in the signal chain. Cumulation and circulation of acoustic energy in the room is done and explored with this elemental mechanical/acoustical spatialization method.

Each robotic object is independently controlled via ARM MCU placed in the body of each object. Timing (on/off states) and rotation speed are “randomly” generated. (Dis)harmony of three elements in space are evolving over time in softly unpredictable algorithmic way. Beside the mechanical sounds of the stepper motors there are also synthesized basic sound signals (sine, saw, white noise, samples) which are amplified and acoustic waveforms from speakers are reflected and distributed into the space by rotating brass parabola. Perceived generative composition is non-interactive and is putting the technology in a non-human autonomous role.
