Method and system for generating a personalised head-related transfer function

Abstract

An audio personalisation method for generating a personalised Head-Related Transfer Function, HRTF, the method comprising the steps of: obtaining a base HRTF model comprising a first set of parameters; outputting a sound from a virtual sound source according to the base HRTF model, the virtual sound source having an intended virtual position; receiving at least one user indication corresponding to a user virtual position of the virtual sound source, wherein the intended virtual position is different to the user virtual position; updating the first set of parameters to a second set of parameters based on the at least one indication from the user so as to update the user virtual location; and generating a personalised HRTF model comprising the second set of parameters, wherein the difference between the intended virtual position and the user virtual position according to the personalised HRTF model is less than the difference between the intended virtual position and the user virtual position according to the base HRTF model.
