Left and right ear HRTF coefficients are determined for an end user, one each for each of a plurality of head orientations, and provided to the end user on a portable recording medium, or via the Internet, etc. The user can then implement the files on audio played on the user's headphones, with the file corresponding to the user's head orientation being selected as the user moves his head to ensure the sound as perceived by the user remains emanating from a fixed external location. The user's personal HRTF may be generated using panoramic images of the ears, such as multiple 2D images or 3D imaging.
