WeatherPlayer (Installation/Performance by Owain Rich. UK)

WeatherPlayer is an online audio installation designed to interpret atmospheric conditions as sound, and broadcast it to the Internet. Light, temperature, wind and water sensors are positioned on top of the University of Brighton building, and the resulting signals are converted into MIDI data, and transmitted to a computer program. The software written in the Supercollider audio programming environment uses the incoming data to determine the structure of sound generating algorithms.
The result is a composition with a cyclic structure which mirrors the light cycles of day and night, with sounds which rise and fall with the wind.
