Hooking up Web Audio to WebGL Typography

Sang Won Lee, Georg Essl
This demo introduces programmable text rendering that enables temporal typography in web browsers. Textual interaction is seen not only as a dynamic but interactive process facilitating both scripted and live musical expression in various contexts such as audio-visual performance using keyboards and live coding visualization. We transform plain text into a highly audiovisual medium and a musical interface which is visually expressive by transforming textual properties using real-time web audio signal. Technical realization of the concept uses Web Audio API, WebGL and GLSL shaders. We show a number of examples that illustrate instances of the concept in various scenarios ranging from simple textual visualization, live coding environments and interactive writing platform.
