Electro-Acoustic Tools High-Level Abstractions for Audio Manipulation and Spatialisation Richard Thomas School of Music University of Leeds UK, LS2 9JT Abstract This paper introduces Electro-Acoustic Tools (EAT), a new set of abstractions for composition and diffusion that are currently under development in Pure Data Extended (Pd). EAT is accessible for preliminary educative use, but it also embraces the advanced functionality that Pd can provide for digital signal processing (DSP) effects and spatial- isation. EAT has a modular architecture with in- stance specific MIDI and parameter preset func- tionality to drive open ended applications. EAT may be differentiated from pre-existing abstrac- tion packages by its accessibility, dynamic patch- ing, and flexible multi-point panning behaviours, which are the primary focus of the discussion here.

Keywords Abstractions, spatialisation, dynamic, dyn∼, tools.
