Abstract:
Head related transfer function (HRTF) is widely used in 3D audio reproduction, especially over headphones. Conventionally, HRTF database is acquired at discrete directions and the acquisition process is time-consuming. Recent works have been proposed to improve HRTF acquisition efficiency via continuous acquisition. However, these HRTF acquisition techniques still require subject to sit still (with limited head movement) in a rotating chair. In this paper, we further relax the head movement constraint during acquisition by using a head tracker. The proposed continuous HRTF acquisition technique relies on the activation based normalized least-mean-square (ANLMS) algorithm to extract HRTF on the fly. Experimental results validated the accuracy of the proposed technique, when compared with the standard static acquisition technique.
