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 ...

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.

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.

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.

Method for measurement of head related transfer functions
The Journal of the Acoustical Society of America, 2010Head Related Transfer Functions (HRTFs) of an individual are measured in rapid fashion in an arrangement where a sound source is positioned in the individual's ear channel, while microphones are arranged in the microphone array enveloping the individual's head.

Head-related transfer function interpolation in azimuth, elevation, and distance
The Journal of the Acoustical Society of America, 2013Although distance-dependent head-related transfer function (HRTF) databases provide interesting possibilities, e.g., for rendering virtual sounds in the near-field, there is a lack of algorithms and tools to make use of them. Here, a framework is proposed for interpolating HRTF measurements in 3-D (i.e., azimuth, elevation, and distance) using ...

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.
