The Architecture of Audio Runtimes

This chapter explains how the components of an interactive audio system fit together and what additional sub-systems can be implemented cheaply to make the foundation more practically useful.

The design splits the implementation into two layers. The first is generic to all platforms, written in a portable subset of C++, providing a rich and consistent interface for the game or application audio programmer to work with. It wraps an inner physical layer which tailors the output of the platform-independent logical layer to the most suitable hardware or software interface provided by the platform vendor.
