Diffusion

Performance Practice and Presentation [PPP]  >  Spatialisation  ]

Electroacoustic diffusion refers to the practice of distributing sound throughout a space using multiple loudspeakers, usually with real-time control over the sound levels, equalisation, and placement of the sound. The source material may be live performers, synthesizers, and/or stereo or multi-channel tape recordings. (Source: Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition. Cambridge Street Publishing, 1999 - CSR-CDR 9901)

Well established diffusion systems with evolved performance practice include BEAST (Birmingham Electroacoustic Sound Theatre) developed by Jonty Harrison at the University of Birmingham, UK, the acousmonium (a development of the notion of the loudspeaker orchestra), conceived and developed at the Groupe de Recherches Musicales (Radio France) in the early 1970s, and the GMEBaphone, IMEB, Bourges, France.
