Image grab from the QuickTime Frequency and Volume


Frequency and Volume is composed of 48 radios, which can potentially all be tuned to different channels simultaneously. The 90-metre long arc of the gallery wall becomes a visual and sonic representation of London’s radio spectrum, constantly changing according to the physical position of its visitors.

On entering the space, participants’ shadows are cast on the wall. Monitored by a video tracking system, each shadow tunes in to a radio frequency, changing channels as it moves around the gallery. The outline of a projected shadow affects the tuning, while its size controls the volume, thus the human body becomes an antenna able to tune into different frequencies. The resulting sound environment is a continuously evolving composition created by multiple contributors .
