the test pattern project
test pattern is a system that converts any type of data (text, sounds, photos and movies) into barcode patterns and binary patterns of 0s and 1s. Through its application, the project aims to examine the relationship between critical points of device performance and the threshold of human perception. The project varies in different formats; audiovisual performance, installation, CD release etc.

This latest audiovisual work from Ryoji Ikeda, presents intense flickering black and white imagery, which floats and convulses in darkness to a stark and powerful, highly synchronized soundtrack. ?Through a real–time computer programme, test pattern converts Ikeda's audio signal patterns into tightly synchronized barcode patterns on screen. The velocity of the moving images is ultra–fast, some hundreds of frames per second, so that the work provides a performance test for the audio and visual devices, as well as a response test for the audience's perceptions. ?test pattern is the third audiovisual concert in Ikeda's datamatics series, an art project that explores the potential to perceive the invisible multi–substance of data that permeates our world.? Taking various forms – installations, live performance and recordings – test pattern acts as a system that converts any type of data (text, sounds, photos and movies) into barcode patterns and binary patterns of 0s and 1s. The project aims to examine the relationship between critical points of device performance and the threshold of human perception, pushing both to their absolute limits.
born in 1966 in Gifu, Japan
live and work in Paris, France
Japan’s leading electronic composer and visual artist Ryoji Ikeda focuses on the essential characteristics of sound itself and that of visuals as light by means of both mathematical precision and mathematical aesthetics. Ikeda has gained a reputation as one of the few international artists working convincingly across both visual and sonic media. He elaborately orchestrates sound, visuals, materials, physical phenomena and mathematical notions into immersive live performances and installations.
Alongside of pure musical activity, Ikeda has been working on long-term projects through live performances, installations, books and CD’s such as 'datamatics' (2006-), 'test pattern' (2008-), 'spectra' (2001-), ‘cyclo’ a collaborative project with Carsten Nicolai, and ‘superposition’ (2012-). He perform and exhibit worldwide such at Museum of Contemporary Art Tokyo; Singapore art Museum; Ars Electronica Center, Linz; Elektra Festival, Montreal; Grec Festival, Barcelona; Aichi Triennale, Nagoya; Palazzo Grassi, Venezia; Armory Park Avenue, New York; Barbican Center, London; Museo de Arte, Bogota; Hamburger Bahnhof, Berlin; DHC/Art Montreal; Laboral, Gijon; Festival d’Automne, Paris among others. In 2013, his works are presented in SRTP Festival Eindhoven, Sarjah Biennale, Frac Franche Comté, Besançon; Carriageworks Sydney, Auckland Triennale; Dark Mofo Festival and Mona Museum, Hobart Tasmania; Festival de Marseille, Borusan Contemporary Istanbul; Ruhrtriennale, Duisburg; Telefonica Foundation Madrid; Kyoto Experiment Festival, Koyanagi gallery Tokyo. His albums +/- (1996), 0°C (1998), matrix (2000), dataplex (2005) and test pattern (2008) - pioneered a new minimal world of electronic music through his razor-sharp technique and aesthetics. www.ryojiikeda.com
