This is a joint session consisting of two 30-minute lectures, "Theatrical Interactivity in Video Game Music" and "Good, Fast Audio Implementation for 3D Games and VR".Theatrical Interactivity in Video Game Music John Robert Matz (Composer, Independent)Modern video game scores have advanced far beyond simple loops. A skilled composer can write music for any scenario the player might encounter, and current technology allows for astounding levels of control and elegant, musical transitions and interactivity between game and score. In this talk, John will examine multiple techniques for crafting reactive scores, from strategic decisions on overall structure, to the use of middleware, to compositional choices that can increase flexibility while reducing player ear-fatigue and enhance emotional, dramatic impact.Good, Fast Audio Implementation for 3D Games and VREmily Ridgway (Composer, Valve Software)This session outlines techniques to achieve immersive audio coverage in your 3D game or VR project quickly and to a high level of quality. Emily will cover both basic and detailed implementation strategies that allow sound designers and non-sound designers to scale audio quality according to their constraints. Examples will be demonstrated in Unity.
