Abstract

Topographic synthesis involves the distribution of ar- rayed structures of parameter values for simultaneous synthesis processes assigned to different channels in a multi-loudspeaker system. In this model, the concept of sound synthesis extends to the design of spatial texture, and morphology is considered not only as change in sound over time, but also as an instantaneous difference in spatially distributed simultaneous sound. The term topography, here, refers to the sonic relief articulated across the perspectival field – the array of possible sonic spatial perspectives within a loudspeaker system – as spatial configurations are shifted over time. The paper presents a set of algorithms which distribute relative properties of texture in multichannel speaker arrays, es- pecially relevant to high density loudspeaker arrays (HDLA), some of which have non-linear, self-organising properties. The processes have been designed in Super- Collider, for a flexible live context, but can be applied in fixed media composition as well.
