1. A computer-implemented method for generating a personalized head-related transfer function (HRTF) for a user, the method comprising:
causing an audio driver within a headphone system to transmit a stimulus signal towards an ear of the user,
capturing a response signal to the stimulus signal;
determining a first HRTF based on the stimulus signal and the response signal;
generating an inverse filter based on the stimulus signal, the response signal, and a headphone transfer function (HPTF) associated with the headphone system; and
generating the personalized HRTF for the user based on the inverse filter and the first HRTF.
