An audio localization test comparing accuracy of static and moving sound sources was carried out in a spatially immersive virtual environment, using loudspeaker array with vector based amplitude panning for virtual sound sources. Azimuth and elevation error in localization were measured. Different sound signals were compared as well. As was expected errors in azimuth localization accuracy were smaller than errors in elevation accuracy. There were more localization blur with virtual sound sources than sound sources reproduced directly from a single loudspeaker. Moving sound sources were localized as well as static panorated sound sources. Although the sound sources moved steadily, the measurements indicated that subjects perceived the changes in sound source location stepwise.
