Localization using nonindividualized head-related transfer functions
The Journal of the Acoustical Society of America, 1993A recent development in human–computer interfaces is the virtual acoustic display, a device that synthesizes three-dimensional, spatial auditory information over headphones using digital filters constructed from head-related transfer functions (HRTFs). The utility of such a display depends on the accuracy with which listeners can localize virtual sound

A Splicing Interpolation Method for Head-Related Transfer Function
2018We proposed a new head-related transfer function (HRTF) interpolation method based on splicing. The sound spreads from sound source to listener’s ears, the wave of head-related impulse response (HRIR) clearly indicates time delay which can be symbolized by the sample number of the first obvious peak and the signal filtered by the diffraction and ...

Spatial Characteristics of Head-Related Transfer Function
Chinese Physics Letters, 2005The spatial characteristics of head-related transfer functions (HRTFs) are studied by a spatial Fourier analysis. A law of the HRTF spatial sampling in different elevation planes is obtained, and the corresponding spatial interpolating method used to recover the continuous HRTF is proposed.

On the spatial symmetry of head-related transfer functions
Applied Acoustics, 2013Abstract The spatial symmetry of head-related transfer functions (HRTFs) in the horizontal and median planes was investigated using an asymmetry coefficient derived from cross-correlation analysis. Statistical results from 52 human subjects show that, for an asymmetry coefficient below 0.05, the horizontal-plane HRTFs are approximately left–right ...

Directional information in head related transfer functions
2004 IEEE Region 10 Conference TENCON 2004., 2004The synthesis of spatial sound, which is played through the headphones, can be done by the use of head related transfer functions (HRTF). The latter describe the changes in the sound wave as it propagates from a spatial sound source to the human eardrum.

Analysis of Korean head-related transfer function
The Journal of the Acoustical Society of America, 2012It is necessary to construct head-related transfer function database for rendering and studying three dimensional audio. For this reason, many research groups have tried to develop a HRTF measurement system and to construct a HRTF database for their research.

Optimization of Head-related Transfer Function (HRTF) Models
2019 IEEE 9th International Conference on Consumer Electronics (ICCE-Berlin), 2019This paper presents a deep-learning technique for modeling Head-related Transfer Function (HRTF) using a large data-set from IRCAM [7] of 49 subjects with 115 directions/subject. We use a log-spectral distortion metric that we have used to optimize the performance of the deep-learning model.

Head-Related Transfer Functions in the Near Field
1998Abstract : Although researchers have long recognized the unique properties of head-related transfer functions (HRTF) in the near field (within 1 m of the listener's head), virtually all of the HRTF measurements described in the literature have focused on source locations 1 m or farther from the listener.
