Indistinct images are projected onto a large screen, accompanied by inarticulate sounds reverberating across the entire exhibition space. All of these images and sounds are created by disassembling and recomposing algorithmically in real- time from vast amount of video materials that are picked up from the internet continuously over the period of the exhibition. The fragmented videos that provide the visual and acoustic source material are recomposed/reordered based on their respective data of luminance and sound (magnitude/level) to create a sine wave, which means that the original videos are deprived of their meaning, and reduced to abstract elements of light and sound for the construction of a sine wave. While all sounds in the world can be represented through combinations of multiple sine waves, in this work a single sine wave is produced by cutting and connecting large amounts of source material.

This sound installation consists of four loudspeakers that play sine waves in a small concrete-walled room. Frequency responses were measured beforehand at each point on a 30 x 30 cm grid in the exhibition space. Based on these measurement results, revealed the spatial “deviations” that found the characteristic frequencies and combinations of these create the space’s distinctive sound. Even though the individual sounds themselves do not change, together they make up a dynamically transforming sound field in which sounds intensify or cancel out each other depending on the listening position in the room. While walking around the space of four invisible layers of sine waves, visitors discover and explore their own individual narratives, the characteristics of hearing, the interaction of sine waves, and the acoustics of the space itself.

The essence of the piece is a set of devices that translate the progression of the sun into the spatiality of sound. Each device consists of a solar panel which actuates an oscillator which then produces a sine wave through a speaker. The amount of light picked up by the solar panel regulates the volume – the objects only play a sine wave when exposed to strong light (e.g. sunlight).

Each participant who enters the space may choose a location for a new device and faces the collective sound of the sine waves produced by the irradiated objects which have already been placed. The sine waves produced by each participant accumulate over the exhibition period of the piece.

The installation The SINE WAVE ORCHESTRA mediate accumulates sequences of sine wave alterations in time. Eight pillars, each with one loudspeaker and one touch sensitive motorized fader, record and play back, audibly and physically, the visitor’s interaction with the frequency changing fader. Each visitor can intervene the looped playback and insert their own trace.
