Natural magnetic fields are described by NASA scientists.

Brilliant Noise takes us into the data vaults of solar astronomy. After sifting through hundreds of thousands of computer files made accessible via open access archives, Semiconductor have brought together some of the sun's finest unseen moments. These images have been kept in their most raw form, revealing the energetic particles and solar wind as a rain of white noise. This black and white grainy quality is routinely cleaned up by NASA, usually hiding the processes and mechanics in action behind the capturing procedure. Most of the imagery has been collected by satellites orbiting the Earth as single frames, or files of information, that are then reorganised into spectral sequences. The soundtrack brings to light the hidden forces at play upon the solar surface, by directly translating the intensity of the brightness into audio manipulation.

A short films where cities are made of and controlled by sound. Every detail of an urban landscape is built by the sonic pressures of an oncoming electrical storm. The very fabric of this isolated world is defined by the noises and frequencies that surround a space in another aural dimension. Semiconductor wrote a program which listens to the various parts of the soundtrack and constructs the animated environments.

Retropolis is a city where the dust never settles and the last few light bulbs are fighting for survival. Transforming London into a modern Sci-Fi landscape, a fast moving journey takes us through destruction and chaos fuelled by an electrically charged soundtrack.

20 Hz observes a geo-magnetic storm occurring in the Earth's upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.

Black Rain is sourced from images collected by the twin satellite, solar mission, STEREO. Here we see the HI (Heliospheric Imager) visual data as it tracks interplanetary space for solar wind and CME's (coronal mass ejections) heading towards Earth.

Heliocentric uses time-lapse photography and astronomical tracking to plot the sun’s trajectory across a series of landscapes. The entire environment feels to pan past the camera whilst the sun stays in the centre of each frame, enabling us to gauge the earth’s rotation and orbit around the sun. As the Suns light becomes disrupted by passing weather conditions and the environment through which we encounter it, it audibly plays them as if it were a stylus.

Presented as a fictional documentary, the sound film All the Time in The World sees the millions of years that have shaped and formed the land, played out at the speed of sound. Semiconductor have reanimated Northumbria’s epic landscape using data recordings from the archives at the British Geological Survey in Edinburgh. This data of local and distant seismic disturbances has been converted to sound and used to reveal and bring to life the constantly shifting geography around us. We follow the motion of the sound as it travels from the coast at Cocklawburn to the hills of The Cheviots, transforming the land. We travel to Abb’s Head and witness Earth Lights, made visible by the seismic sounds. These phenomena are said to be the result of tectonic movement in the strata below us. Flashes of light and electricity are produced as movement squeezes mineral crystals together, displaying luminous objects whose motion coincides with the direction of ruptures within the earth.

By asking a group of space physicists the unanswerable, Semiconductor reveal the hidden motivations driving scientists to the outer limits of human knowledge. In an attempt to find meaning within the question, they open a Pandora’s Box of limitations within science itself, revealing their own philosophical confines. Issues of faith, medicine and the laws of matter are raised to illustrate the infinitely complex universe we live in.

The Sound of Microclimates reveals the sights and sounds of a series of unusual weather patterns in the Paris of today. Here, architecture has become interwoven with the natural processes of the geographical landscape. Set within the un-noticed moments in time, extreme microclimates are presented as the future in city accessories, revealing the unseen urban terrains of tomorrow. Like the temporary staged events at an World Expo these weather patterns hi-light public spaces and architecture within the city of Paris. They exist as a series of weather observations that animate the evolution of the inanimate urban condition. Each microclimatic intervention has its own audible frequencies, where the sound from each environment animates the movement and reveals each sites unique narrative.
