Fast and Accurate High-density Hrtf Mea- Surements Using Generalized Frequency- Domain Adaptive Filter
High-Density (HD) Head-related transfer function (HRTF) measurements are extremely timeconsuming and complicated. This problem can be solved by continuously rotate a dummy head and using on-line de-convolution of binaural signals to obtain the HD HRTFs. In this work, we use a generalized frequency-domain adaptive filter (GFDAF) for HD HRTF measurements, which has significant better convergence ...
متن کاملEvaluation of HRTF Data using the Head-Related Transfer Function Differences
A simple spectral computation method is introduced for the evaluation of differences in dummy-head Head-Related Transfer Functions (HRTFs). These transfer functions describe the directional-dependent filtering of the outer ears and are responsible for basic localization cues. Head–Related Transfer Function Differences (HRTFDs) are defined as the quotient of measured HRTFs in the same direction,...
متن کاملMultiple Exponential Sweep Method for Fast Measurement of Head-Related Transfer Functions*
Presenting sounds in virtual environments requires filtering free-field signals with headrelated transfer functions (HRTF). HRTFs describe the filtering effects of pinna, head, and torso measured in the ear canal of a subject. The measurement of HRTFs for many positions in space is a time-consuming procedure. To speed up the HRTF measurement, the multiple exponential sweep method (MESM) was dev...
متن کاملDesign of a Fast Broadband Individual Head-Related Transfer Function Measurement System
In order to improve the quality of binaural based virtual reality systems, the use of individual headrelated transfer functions (HRTF) plays a major role. This paper presents a system for individual HRTF measurements developed at the Institute of Technical Acoustics in Aachen. The main characteristic of this system is the close distance between head and sound sources. This allows to make use of...
