_an analog memory
Every given (data) is syntactically encoded and requires a body, which may function as medium, or as storage memory. The body may be long-lasting or short-lived.
_a homeostatic machine
In this piece, the body consists of acoustic waves which are channelled through a system of tubes. A circular causal process is required in order to transform this short-lived body into a long-lasting one. This feedback has explosive and implosive properties; therefore, a self-regulating system is implemented, preserving the physical equilibrium through observable and dynamic behaviour. Only then can the body be used as storage memory.
_an acoustic delayline
A codified audio signal circulates in a closed (feedback) system, consisting of a computer, a speaker, 246 meters of copper tube and a microphone. By using the acoustic delay of the tube system, it is possible to store data. The longer the tube, the greater the time delay, which leads to greater memory capacity. In 246 meters of tube, the delay is approximately 0.8 seconds. This corresponds to approximately 1 Kbit memory capacity.
Yunchul Kim (Korea/Germany) studied music composition in Seoul and Media art at KHM (Kunsthochschule für Medien Köln). Now he is a guest teacher at Merz Akademy in Stuttgart, Germany.
