This has long been a restriction, but now with more powerful computers this is becoming a lesser and lesser concern and software solutions are now applicable. Most current virtual environment applications do not take advantage of these implementations of accurate spatial cues, however. This paper compares a common implementation of spatial audio and a head-related transfer function (HRTF) system implementation in a study in relation to precision, speed and navigational performance in localizing audio sources in a virtual environment. We found that a system using HRTFs is significantly better at all three performance tasks than a system using panning.
Differences in human audio localization performance between a HRTF- and a non-HRTF audio system

This paper addresses the differences in aurallyaided visual search performance between a HRTF enhanced audio system (3D) and an amplitude panning audio system (panning) in a virtual environment. We present a performance study involving 33 participants locating aurally-aided visual targets placed at fixed positions, under different audio conditions. A varying amount of visual distractors were present, represented as black circles with white dots. The results indicate that 3D audio yields faster search latencies than panning audio, especially with larger amounts of distractors. The applications of this research could fit virtual environments such as video games or virtual simulations.
