Claim 19:
20. A system, comprising:
a memory that stores a calibration engine; and
a processor that executes the calibration engine to perform the steps of:
transmitting, using a first audio driver within a headphone system, a stimulus signal towards a first ear of a user;
capturing a response signal at the first ear of the user in response to the stimulus signal;
generating response data based on the stimulus signal and the response signal;
generating a target HRTF based on the response data, wherein the target HRTF characterizes at least one physical attribute of the user;
generating an inverse filter based on the response data and based on a headphone transfer function (HPTF) associated with the headphone system; and
generating a personalized HRTF for the user based on the inverse filter and the target HRTF.
