Duncan Speakman (UK 1976) originally trained as a sound engineer at the Liverpool Institute for Performing Arts. Since 2005 he has focused on mobile audio and locative media, creating socially relevant experiences that engage audiences emotionally and physically in uncontrolled spaces. From 2010-2016 he was director of the arts collective Circumstance, regularly presenting work internationally including installations on trains in Guangzhou, loudspeaker symphonies in New Zealand, audio walks in Saitama and sound installations in Porto. Recently he has developed a number of hybrid print and audio experiences such as It Must Have Been Dark By Then. He is currently a PhD candidate within the 3D3 programme, researching compositional approaches to mobile sound led experiences, and what these might offer to contemporary ecological debate. Within narratives of experience, he wraps his questions in melancholy and romance.
