Abstract:
In this paper, I present a prototype of my audio-visual granular synthesis instrument Kortex. The instrument enables real-time improvisation of audio-visual material in a performance context. Granular synthesis is a processing technique that segments media into thousands of individual pieces and is used during the performance to manipulate audio and visual material on micro time levels (1-100ms). The performance demonstrates an approach to real-time improvisation of audio-visual granular synthesis and aims to illustrate an alternative form of interactive entertainment. A single performer embodies the role of both the musician and visual artist simultaneously, contrasting the usually separate audio and visual roles found in the contemporary DJ and VJ scene. The integrated audio-visual performer is then able to communicate ideas and meaning to an audience with the help of both senses at once.
