Abstract

Immersive audio systems are being envisioned for applications that include teleconferencing and telepresence; augmented and virtual reality for manufacturing and entertainment; air traffic control, pilot warning, and guidance systems; displays for the visually-impaired; distance learning; and professional sound and picture editing for television and film. In this paper we examine signal processing issues that pertain to immersive audio rendering over loudspeakers. We propose two methods that can be used to implement the necessary filters for generating virtual sound sources based on synthetic head-related transfer functions with the same spectral characteristics as those of the real source. Furthermore, several factors are presented that pertain to high quality immersive audio reproduction at the desktop including acoustical and psychoacoustical considerations and the importance of dynamically adapting to listener’s head movement.
