Constraints and opportunities: managing complexity. Learning through play. Software and hardware mixing. Disc and memory capacities. Curves, synergies and neat tricks.
Big business: sales in millions, billions of turnover, teams of hundreds working for years on multiple implementations of each product.
Scalability: from a dozen voices on old phones to hundreds on recent PCs and consoles, in mono, 3D surround sound, both or anything in between. Differences in listening practice between console and PC gamers.
Psychoacoustic dimensions: distance, direction, environment, intensity, motion, pitch.
Human dimensions: threats, opportunities, choices, risks.
Audio system layering: interaction with controllers, physics, game logic, networks and audio endpoints like loudspeakers and headphones.
Logical abstractions: listeners, soundbanks, effects, Virtual Voices, groups and reporting.
Physical sub-systems: panning, mixing, filtering, reverb and monitoring of sound sources.
Pervasive interactivity: the applicability of new tools to old media.
