Spatialisation is perhaps the most all-embracing and general term used to describe the means by which loudspeakers are used to articulate or create a spatial musical experience for listeners in playback or performance. The term is wide-ranging from a technical, and arguably aesthetic point of view. It includes formats (e.g. Stereophonic, Ambisonic, Dolby), the placement and movement of sounds in space in any number of listening situations (e.g. concert hall, installation, virtual environment, cinema), and performance practices (e.g. diffusion, Octophony, and more recent developments in automated performance systems).
