Speak - active sound-space and the performer

Speak is an interactive work for meta- trumpet and active sound space – the assem- blage of instrument, computer and physical acoustic environment. A sound-as-medium con- cept is implemented using an ALife wave model inhabited by an evolving population of sound- ing-listening agents. The work consists of layers of different wave phenomena, enacted by these agents. Listening within the system is considered important in the encouragement of emergence, as is the redescription of phenomena between different domains. In Speak, communication be- tween three domains – wavespace, performance space and symbol space – produces a complex hybrid dynamical system.
