Play audio sample from 'Chronotop'


Ambisonic Tape

The Chronotope Installation is based on a time-delayed feedback network. The structure of the network is composed of different nodes connected by delay lines ranging from 50 milliseconds up to 20 seconds. The control parameters of the nodes are threshold, attack, and decay time. The control parameters of the delay lines are delay time and attenuation. The network is excited by a short percussion signal. I aligned the parameters in such a way that different sonic layers emerge and change through the piece enhancing the static character by a progressively changing transformation. The movements and the permanent rotations of the sound layers in the three-dimensional space simulate the feedback loops in the time and shape the sound plastically and vividly.

The sounds we perceive in everyday life range from very dominant sounds to sounds which can be subconsciously ignored. This creates an impression of a hierarchically structured acoustic panorama, which is divided into an acoustic foreground and background. Foreground noises, such as warning signals, sounds which helps us to orient ourselves as well as other loud and nearby noises are perceived clearly. On contrary, sounds and signals which are not necessary for orientation as well as quiet and remote noises are likely to be suppressed.

This hierarchy of sounds played an integral role in my installation, being part of the Blicklandschaften exhibition initiated by the Department of Landscape Architecture at the ETH Zurich. Furthermore, the Polyterrasse with its exceptional location, its spatial expansion and the setup of various boxes and containers inspired me to transform the place into a spacious stageset in public space. Moving sounds were distributed across the entire terrace by eight wooden boxes containing loudspeakers. Thus, the theme of perceiving soundscapes and the sound material, transformed into a musical form, were combined with a spatial concept.
