Spatial frequency response surfaces: an alternative visualization tool for head-related transfer functions (HRTFs)
نویسندگان
چکیده
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 well-known HRTFrelated psychophysical phenomena due to head, torso, and pinna filtering. Finally, these surfaces suggest an interpolation algorithm by which Directional Transfer Functions (DTF’s) corresponding to arbitrary spatial locations can be computed from existing DTF measurements at known locations.

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...
متن کاملAccelerated Method for the Reduced-Parameter Modeling of Head-Related Transfer Functions for Customizable Spatial Audio
Many spatial audio (“3D sound”) systems are based on the use of Head-Related Transfer Functions (HRTFs). Since the measurement of these HRTFs for each prospective listener is impractical in many applications, developers frequently use “generic” HRTFs (e.g., from a mannequin), sacrificing the superior spatialization that could be provided by “individual” HRTFs. This paper presents an improved me...
متن کاملInterpolation of Head-Related Transfer Functions
Using current techniques it is usually impractical to measure head-related transfer functions (HRTFs) at a spatial resolution that does not exceed the minimum audible angle, i.e. 1-2° for a source directly in front, by a considerable amount. As a result, measured HRTFs must be interpolated to generate a display in which auditory space is rendered smoothly. The spatial resolution at which it is ...
متن کاملVisualization and dereverberation of head-related transfer function based on spatio-temporal frequency analysis
A new method of visualizing characteristics of head-related transfer function (HRTF) is proposed. The proposed visualization method can illustrate the HRTFs and other factors such as the reverberations separately. The HRTF is an acoustic transfer function between a sound source and the ear canal entrance, and it is defined as a function on time and direction of the sound source. Since the HRTF ...
متن کاملUsing computer vision to generate customized spatial audio
Creating high quality virtual spatial audio over headphones requires real-time head tracking, personalized head-related transfer functions (HRTFs) and customized room response models. While there are expensive solutions to address these issues based on costly head trackers, measured personalized HRTFs and room responses, these are not suitable for widespread or easy deployment and use. We repor...
