- Additional information
- This output comprises two works for Expanded Audiovisual Format (EAF) installation, Alocas (2017) and Visaurihelix (2018), and an accompanying book chapter from Sound/Image: Aesthetics and Practices (2020). The output includes both works in single-channel video and stereo audio format, documentation of the works in installation, detailed descriptions of both works, and the accompanying book chapter. The chapter defines and discusses the terms Expanded Audiovisual Format (EAF), site-specific and site-adaptive works, and algorithmic aleatoricism in relation to the composition of Alocas and Visaurihelix as well as in the context of contemporary audiovisual practices more broadly. Alocas and Visaurihelix engage with Demer’s (2010) notions of site, in ways that are site-adaptive (Alocas) and site-specific (Visaurihelix) respectively. They were composed using a technique defined in the book chapter as algorithmic aleatoricism, where sonic and visual materials are generated first algorithmically in Max and Processing, and subsequently intervened in using chance-based procedures – specifically through elements of semi-random or chaotic behaviour built into the algorithmic systems themselves. In Alocas, for example, the pitches used in the synthesised tone clusters are defined algorithmically. Subsequent interventions into these clusters, particularly by vocal or instrumental materials, are mapped to the timings of unpredictable behaviours in the visual system – generating a recursive form of algorithmic aleatoricism across the audiovisual domain. As discussed in the chapter, this compositional strategy enables the composer to develop the overall compositional design, whilst allowing elements of fine detail within the materials to arise out of chance and rules-based procedures.
