Method and system for generating transfer function related to the head by linear mixing of transfer functions related to the head

摘要

A method for determining a head-related transfer function (HRTF), said method including the step of: (a) performing, in response to a signal indicative of a direction of arrival, a linear mixture using data from a set of functions HRTF coupled to determine an HRTF function for the arrival address, wherein the set of coupled HRTF functions comprises data values that determine a set of coupled HRTFs functions, the set of coupled HRTFs functions comprising a set of coupled HRTFs functions of the left ear and a set of HRTFs functions coupled to the right ear for the arrival address, where the coupled HRTFs functions are determined from normal HRTFs functions for the same arrival addresses by modifying the phase response of each normal HRTF function above a coupling frequency such that the difference between the phase of a function HRTF ac The left ear and a HRTF function coupled to the right ear for the same direction of arrival are at least practically constant as a function of frequency, for all frequencies practically above the coupling frequency.
