The ultimate goal of virtual acoustics is to simulate the complex acoustic field experienced by a listener freely moving around within an environment. This paper discusses some of the engineering constraints that may be faced during implementation and the perceptual consequences of these constraints. In particular, system parameters like the update rate and overall system latency of interactive spatial audio systems are defined and their perceptual counterparts are discussed.
