Adventures in spatial audio across three acousmatic works: discoveries and new directions.

Abstract

This presentation explores compositional approaches to space and spatialisation in three multichannel acousmatic electroacoustic works. It begins with Pellere (2011–12), an 8-channel piece using open-source software, focusing on stereo sound deployment alongside the development of 8-channel spatial sound identities. The discussion then shifts to Traces of Play (2016–17), a 4-channel work composed with a 5.1 system, examining how adopting reduced fixed-format speaker configurations impacts on spatial creativity. Finally, Reflecting Cau Cau and Parque Urbano del Bosque (2021) uses ambisonic techniques, highlighting unique spatial manipulations and workflow changes. The presentation concludes by discussing hybrid approaches currently under development that integrate ambisonic and channel-based techniques into compositional workflows.
