Abstract
A system for generating a head-related transfer function, HRTF, for a given position with respect to a listener, the system comprising a dividing unit operable to divide each of a plurality of existing HRTFs, each corresponding to a respective plurality of positions, into first and second components, an interaural time difference determination unit operable to determine an interaural time difference expected by a user for a sound source located at the given position in dependence upon the respective first components, an interpolation unit operable to generate an interpolated second component by interpolating generated second components using a weighting dependent upon the respective positions for the corresponding HRFTs and the given position, and a generation unit operable to generate an HRTF for the given position in dependence upon the interaural time difference and the interpolated second component.
