<p>A method of modifying an original head-related transfer functions (HRTF) for a standard dimensioned head, the HRTF comprising a near-ear response function, a far-ear response function, and an inter-aural time delay (ITD), the modified HRTF being such as to resemble an HRTF approximating that derived for a listener having different head and/or ear dimensions to the standard dimensions, the method including one or more of the steps a) multiplying the ITD value of the HRTF by a given scaling factor independent of frequency, b) multiplying the near ear and/or far ear response function of the HRTF by a constant scaling factor in the frequency domain independent of time delay, such as to expand or compress the said function(s) in the frequency domain, c) providing the near ear and/or far ear response function of the HRTF with a positive or negative offset value in the frequency domain, and d) multiplying the amplitude of the near ear and/or far ear response function of the or each original HRTF by a given gain factor. <IMAGE></p> |
