Interpolating Head Related Transfer Functions
This paper describes the interpolation of head related transfer functions (HRTFs) for all directions. The interpolation of HRTFs enables us to reduce the number of measurements for new user’s HRTFs, and also reduce the data of HRTFs in auditory virtual systems. A linear interpolation and the spline interpolation are evaluated and the advantages of both methods are clarified. The interpolation m...
متن کاملModeling Head Related Transfer Functions
Head Related Transfer Functions (HRTF’s) characterize the transformation of a sound source to the sounds reaching the eardrums, and are central to binaural hearing. Because they are the result of wave propagation and difiraction, they can only be approzimated by finitely parameterized filters. The functional dependence of the HRTF on azimuth und elevation is described, the requirements for a mo...
متن کاملApproximation of Head Related Transfer Functions
The set of Head Related Transfer Functions (HRTF) enables the generation of spatial sound [1]. Two FIR filters with 512 coefficients are required for any spatial position. This paper suggests a method for the description of HRTFs which reduces the total number of necessary coefficients for the factor 4.5 – 14 and enables the construction of new filters for nonmeasured positions. The method expl...
متن کاملWavelet Analysis of Head-related Transfer Functions
The directional-dependent information in the head-related transfer function (HRTF) is important for the study of human sound localization system and the synthesis of virtual auditory signals. Its time-domain and frequency domain characteristics has been widely studied by researchers. The purpose of this paper is to explore the ability of discrete wavelet transform to describe the timescale char...
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 ...
