چکیده

This letter documents the design and implementation of a tool which facilitates a new method of visualizing and sonifying Head-Related Transfer Function (HRTF) data sets. HRTF’s are empirically measured digital filters used in binaural spatialized audio systems which simulate the direction-dependant acoustic filtering properties of the human external ear. Because HRTF data sets are often reported as functions of three variables (azimuth angle, elevation angle, frequency), we suggest that three-dimensional, volumetric visualization tools can be effectively used to gain quick intuition about the structure of these large, complex data sets. Specifically, our visualization tool allows simultaneous visual and aural exploration of HRTF data by processing sounds with HRTF’s selected directly from volumetric displays of HRTF data.

Spatial Frequency Response Surfaces (sfrs’s): an Alternative Visualization and Interpolation Technique for Head-related Transfer Functions (hrtf’s)

This paper introduces Spatial Frequency Response Surfaces (SFRS’s), an alternative, spatial-domain visualization tool for head-related transfer functions (HRTF’s). Qualitative analysis of SFRS’s is easier than direct comparison of HRTF magnitude responses, and reveals many cross-subject similarities in HRTF data corresponding to well-known HRTFrelated psychophysical phenomena. We present an SFR...

Spatial frequency response surfaces: an alternative visualization tool for head-related transfer functions (HRTFs)

This paper presents an alternative visualization tool for headrelated transfer functions (HRTF’s) which represents HRTF data sets as magnitude spatial frequency response surfaces. Qualitative analysis of HRTF data is easier in the spatial domain than in the magnitude frequency domain and allows quick comparisons between different subjects’ HRTF sets. In addition, these surfaces exhibit many wel...

INTRODUCTION TO HEAD-RELATED TRANSFER FUNCTIONS (HRTF’S): REPRESENTATIONS OF HRTF’S IN TIME, FREQUENCY, AND SPACE (invited tutorial)

This tutorial provides an introduction to Head-Related Transfer Functions (HRTF's) and their role in the synthesis of spatial sound over headphones. We define HRTF’s and discuss how they provide spectral cues which reduce the ambiguity with which the classical duplex theory decodes a free-field sound’s spatial location. We describe how HRTF’s are measured and how they are typically used to synt...

Common-acoustical-pole and zero modeling of head-related transfer functions

Use of a common-acoustical-pole and zero model is proposed for modeling head-related transfer functions (HRTF’s) for various directions of sound incidence. The HRTF’s are expressed using the common acoustical poles, which do not depend on the source directions, and the zeros, which do. The common acoustical poles are estimated as they are common to HRTF’s for various source directions; the esti...

Common-acoustic-poles/zeros approximation of head-related transfer functions

Common-acoustic-poles/zeros (CAPZ) approximation is a more efficient way to model head-related transfer functions (HRTF’s). In CAPZ approximation, a group of HRTF’s can share a set of poles but use their own zeros. Previous CAPZ works, such as the Prony, Shanks and iterative prefiltering methods, were all based on the linearized least-square criterion. A new state-space approach, jointly balanc...
