Eigendynamik [Momentum]

The sound sculpture Eigendynamik by Lukas Reichert portrays a dynamic system created by simulated feedback. A rotating motor makes the steel sheet vibrate, and this is recorded by a microphone. The signal is analysed and interpreted by a computer. The amplitude of the vibration determines the movement of the sheet, the visualization on it, and the motor’s pattern structure. The visualization is a simple wave form representation in real time and in rest periods moves with an intensity determined by the previous sound level. Similarly, the computer uses the amplitude to calculate the length of the next vibration and rest phases. Following a loud signal there is a shorter phase, after a quiet signal, a longer one.
