Abstract

The use of head tracking in binaural synthesis of spatial sound increases the quality of reproduction. The required quality of a head-tracking system for this purpose is the topic of interest in this article. A listening test was performed to evaluate the effect of four common sources of error in head-tracking systems. The listeners rated the naturalness of binaural reproduction in different head-tracking conditions. According to the test, the main requirement for the head-tracking system is to obtain an accurate and unrestricted azimuth angle. Furthermore, lower update rate of the tracking system affects the quality. The results showed prominent dependence on program material and individual differences were present.
