sys_m1 is an eight-minute electroacoustic composition realized using systemic, a real-time composition, performance and spatialisation system controlled via a physics-based visual environment. In systemic, physics-based algorithms govern the behaviour of objects in a visual system (triggered by a human user), and the movement of those visual objects controls the spatialisation of corresponding sound objects over an 8-channel circular speaker configuration. These sound objects can be either synthesized in real-time via the software controlling the sonic trajectories (puredata) or can trigger the playback of pre-composed sound objects. sys_m1 is composed from a number of recordings taken from systemic. The sonic material is a combination of pre-composed sound objects and real-time synthesized sound, with Doppler shift added according to speed and trajectory. By utilizing a physics-based visual system to control the spatialisation of sound, I am effectively removing decision-making from the spatialisation process, often seen as an extension of electroacoustic composition. Here, spatialisation of objects is aleatoric, raising questions about the nature of the diffusion process more generally.
