Novel Sampling Scheme on the Sphere for Head-Related Transfer Function Measurements

On High-Resolution Head-Related Transfer Function Measurements

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 dimensionali...

A Database of Repeated Head-related Transfer Function Measurements

This paper describes a new HRTF collection, measured at the Music and Audio Research Laboratory (MARL), at NYU. This collection of 40 datasets, consists of repeated HRTF measurements on 4 subjects (10 HRTF sets per subject). Analysis of the data offers an understanding of the expected degree of variation in HRTF sets, which, when supported by subjective evaluation, can provide deeper insight fo...

Analysis of the Spectral Variations in Repeated Head-related Transfer Function Measurements

This paper discusses the range of spectral variations between HRTF sets measured on the same subjects. The analysis is done in a corpus of 40 HRTF datasets of 4 subjects (10 datasets per subject). Variations are observed as a function of frequency, distance of the ears to the sound source (ipsilateral or contralateral), and location. Assessments of the spatial quality of all datasets were made ...

Parallel Monte Carlo Sampling Scheme for Sphere and Hemisphere

The sampling of certain solid angle is a fundamental operation in realistic image synthesis, where the rendering equation describing the light propagation in closed domains is solved. Monte Carlo methods for solving the rendering equation use sampling of the solid angle subtended by unit hemisphere or unit sphere in order to perform the numerical integration of the rendering equation. In this w...
