This paper deals with two important questions associated with HRTF measurement: 1) "what is the required angular resolution?," and 2) "what is the most suitable sampling scheme?." The paper shows that a well-defined finite number of spherical harmonics can capture the head-related transfer function (HRTF) spatial variations in sufficient detail, which is defined as the HRTF spatial dimensionality. For the 20-kHz audible frequency range, the value of the dimensionality means a high-directional...[Show more]
