A system calibrates one or more head-related transfer functions (HRTFs) for a user. An indicator is presented on a head-mounted display, where the indicator prompts the user to turn the user's head to view the indicator and effectively change the user's head orientation. The head orientation corresponds to positions of both ears, thus a position of the indicator prompting to change the user's head orientation is associated with corresponding positions of both ears. Responsive to the indicator being viewed by the user, a sound source at a fixed position transmits a test sound and the test sound is received at microphones coupled to the user's ears. By analyzing the test sound received at the microphones, a unique HRTF associated with a relative position between the sound source and each ear can be obtained.
