Collaborative music composition based on sonic interaction design

Abstract

This work proposes a way to create sonic interaction through collaborative composition of spatialized sounds in real time, based on SID (sound interaction design). There is no centralizing figure for the sound designer, and each person may begin a sonic interaction spontaneous and independently, or join an ongoing interaction. Therefore, each person is responsible for the result of his own interaction. Every movement a person makes within the reach of the determined space, the sound is captured and processed and then externalized as feedback in the multichannel sound system, perceived as a unified sound. The concepts and app designed for sonic interaction discussed in this work is intended for use in multidisciplinary contexts, raising important technical challenges. We have devised a design process resulting in four different prototypes, attending to different perspectives. Each prototype had its own experiment.
