Mapping moving images to microsounds

This presentation covers an overview of the aesthetics and techniques used to map abstract moving images to the electroacoustic music of Curtis Roads and reviews the application of such methods to working with digital audio and video signals. The lecture also provides an overview of several visual works created by Brian O’Reilly in an on-going collaborative project with Curtis Roads, with a selection of works pursued over many years stretching back to 2001 until the present.
The focus will not only be on these experimental visualisations and their use of a diversity of techniques in both the generation of the footage and to how they are analysed and mapped to elements of the sonic landscape created by the electronic sounds, but it will also focus on one of the many goals of technology: the increased precision and ever-finer control of what elements of sound were analysed and how they were mapped to the visual gestures of the moving images.
