Fundamentals of Audio and Video Programming for Games (Pro-Developer)

In this chapter, we described a sample that demonstrates the EAX 2.0 environmental sound settings. The sample demonstrated how to use a property set interface to set one of the predefined environments, and individual settings for obstruction and occlusion . Driving the hardware directly with property sets can create convincing atmosphere and sound effects with very little performance cost.

Coding property sets is fairly easy and, given the high-quality results, is the recommended way to get great environmental sound effects.
