Personalized HRTFs enable elevated externalized spatial audio over headphones
Evidence
Headphone reproduction of binaural or spatial audio is a different, more elevated experience when the content is rendered with personalized head-related transfer functions (HRTFs). HRTFs define interaural time and level differences and spectral cues that allow us to localize a sound source in space. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1690
