Integrated media workstations are increasingly being used for creating
, editing, and monitoring sound that is associated with video or compu
ter-generated images. While the requirements for high quality reproduc
tion in large-scale systems are well understood, these have not yet be
en adequately translated to the workstation environment. In this paper
we discuss several factors that pertain to high quality sound reprodu
ction at the desktop, including acoustical and psychoacoustical consid
erations, signal processing requirements, and the importance of dynami
cally adapting the reproduced sound as the listener's head moves. We p
resent a desktop audio system that incorporates several novel design r
equirements and integrates vision-based listener-tracking for accurate
spatial sound reproduction. We conclude with a discussion of the role
the pinnae play in immersive (3D) audio reproduction and present a me
thod of pinna classification that allows users to select a set of para
meters that closely match their individual listening characteristics.
