3D Virtual Audio with Headphones: A Literature Review of the Last Ten Years
* Presenting author
With the increasing number of applications for virtual reality also the research activity on 3D audio through headphones has risen. Thus, different approaches for improving the perception of the virtual experience have been developed. This paper summarizes and evaluates the work done on this topic during the last ten years. The investigations mainly address the individualization of the binaural technologies for improving the virtual source localization and externalization. These strategies can be basically divided into personalized headphone equalization and individualized head-related transfer functions (HRTFs). The former is responsible for getting rid of the coloration introduced by the headphone used during the playback, and the latter for introducing personal anthropometric characteristics into the utilized HRTFs. At the end, selected approaches are implemented and evaluated.
