Abstract
A HRTF used for 3D spatialized audio is combined with, e.g., by concatenation, additional settings to provide a more comfortable, accessible, and enjoyable experience for a listener such as a player of a computer game listening to audio through a headset. A single transfer function is thus created that includes the other settings, and once the transfer function is computed the run-time processing can be treated as a single combined transfer function rather than multiple separate stages, resulting in computational savings. The additional settings pertain to hearing aids normally worn by the listener as well as a room-related function specific to a particular listening venue.
