SOUND OF LIGHT "Half of the human brain is devoted directly or indirectly to vision" - Mriganka Sur, Professor of Neuroscience, MIT Imagine hearing the colours you perceive. SOUND of LIGHT is a synesthetic sound sculpture which interprets and dynamically transforms solar light into audio frequencies. This organic-inspired structure recontextualizes perception of light and colour by thoughtfully and playfully juggling human sensory inputs. It is an urban installation which focuses on a very specific area – the 1912 music pavilion in Hamm. RGB vs. CMY – sunlight is comprised of a broad spectrum of electromagnetic energy. In essence, it's a huge array of varying frequencies, a staggering amount of white noise with billions of frequencies that can be divided a million of times by distilling sunlight into specific colours. The six hanging, coloured columns of the pneumatic structure – which stand for the primary RGB (red/green/blue) and secondary CMY (cyan/magenta/yellow) colour-models to which the human eye is attuned – are designed to receive those different frequencies and convert them from visible to audible sensory input. A high-quality digital camera with a wide-angle lens mounted on the top of the structure sends a video feed of the sky to a computer running software based on the open-source processing.org development platform. This custom program divides the sky into six sectors which each send a stream of RGB, CMY and brightness data to a second computer dedicated to synthesizing audio. Note intervals, sound dynamics and timbral character are all patched within Ableton Live to react along with fluctuating visible atmospheric conditions. A series of subwoofers is fixed directly on the bottom of each structure and transform its surface into a giant vibrating loudspeaker. The audio-impulses that are synthesized in real-time move through the structure in surround-sound, giving a new perception of space. The whole area is brought alive with a main focus on low-frequency vibrations. The audience can experience a peculiar oneiric reality through the superimposition of colours, shapes, sounds and vibrations within the particular urban context of the local environment. Visitors can have additional complimentary visual experiences by changing their point of view from within the installation. A person can "filter" their surroundings with one single primary or secondary colour, but also mix different ones together. SOUND of LIGHT is a composition of hue, saturation, and light. People always have the possibility to discover their own concert which arises from their unique point of view – an individual spectrum.
