Ritual
Sound Installation [2014,2019]
Ritual is a generative algorithmic sound installation. The process is visualised on a computer display. A ring of eight loudspeakers is mounted in a circle, visitors can experience the installation from the inside or outside of that circle.
The process is simple: eight audio buffers of a few seconds length are filled with a continuous sine wave: each channel with a different frequency and ampltude, directly routed to the eight loudspeakers: Each speaker plays back that single sine wave. In regular intervals, a short segment of time in those buffers is chosen and two randomly selected channels are swapped. This process repeats again and again for quite some time.
At the beginning of the process, each audio channel contains a single sine wave. After a while, the swapping of the buffers will create complex rhythmical patterns, diffused in space. After a much longer while, the signal will turn into a stream of slowly changing colored noise. During the course of the exhibition the ritual is repeated in random intervals (after several minutes, hours or days) and each time a new set of frequencies and amplitudes is chosen.
