W12 - ADAPTIVE MUSIC FOR GAMES: INTERACTIVE XMF IN-DEPTH

Chair:
Chris Grigg, IASIG

Abstract:
The Interactive eXtensible Music Format (iXMF) is the first nonproprietary standard for interactive audio content, recently produced by the Interactive Audio SIG (IASIG). Technical lead Chris Grigg explains iXMF technology and its benefits for audio artists, game designers, and game engine designers. iXMF addresses the difficulty and expense of interactive audio by providing (1) a nonproprietary, cross-platform file format, and (2) an abstract model for the runtime audio engine. The format bundles audio assets with dynamic behavior rules. The model defines how the rules are interpreted in real time to play those assets. Because the model is based on a handful of simple low-level primitives, it is both very portable and very general. Scenario testing indicates any known interactive audio behavior style is possible.
