test pattern [n˚2] presents flickering black and white imagery that floats and convulses in darkness on two screens, one on the floor and another floor to ceiling, in time with a stark, powerful and highly synchronised soundtrack. Through a real–time computer program audio signal patterns are converted into tightly synchronised barcode patterns on the screens. The velocity of the moving images is ultra–fast, some hundreds of frames per second, providing a totally immersive experience for visitors. The work provides a performance test for the audio and visual devices, as well as a response test for one's perceptions.

This audiovisual work presents intense flickering black and white imagery which floats and convulses in darkness to a stark, powerful and highly synchronised soundtrack.
Through a real–time computer program, test pattern converts audio signal patterns into tightly synchronised 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.

In this first edition of the project, an audiovisual installation, test pattern involves a sequence of tests for machines and humans. Comprising of visual patterns converted and generated from sound waveforms in real–time, the installation is made up of eight computer monitors and sixteen loudspeakers aligned on the floor in a dark space. The eight rectangular surfaces of the screens flicker intensely with black and white images. Sixteen channel sound signals are mapped as a grid matrix, passing and slicing the space sharply, and via a real–time computer program the signal patterns are converted into eight tightly synchronised barcode patterns. The velocity of the moving images is ultra–fast, at certain points some hundreds of frames per second, providing a performance test for the devices as well as a response test for visitors' perceptions.
