Sometimes, the most crucial information captured by a video is not the image, but the sounds that are heard ‘off camera’. Similarly, radio communications by police or other emergency services personnel can contain vital evidence, either in what is said, or what is heard in the background.
Forensic Architecture uses a number of techniques to employ audio recordings for investigative ends, including synchronisation, identification of weapons, or using ‘ear-witness’ testimony and ‘echo profiling’ to reconstruct spaces and events through sound.
