Head-tracked HRTF filtering restores realistic external sound localization

Evidence

Using a head tracker, a far more realistic perception of external sound sources can be obtained. In head tracking, the direction of the listener’s head is monitored about 10–100 times a second, and the HRTF filter is changed dynamically to keep the perceived direction of sound constant in the global coordinates (Begault et al., 2001; Breebaart and Schuijers, 2008). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1927
