Perceptual attributes for the comparison of head-related transfer functions [PDF]

The Journal of the Acoustical Society of America, 2016
The benefit of using individual head-related transfer functions (HRTFs) in binaural audio is well documented with regards to improving localization precision. However, with the increased use of binaural audio in more complex scene renderings, cognitive studies, and virtual and augmented reality simulations, the perceptual impact of HRTF selection may ...

A multiple model high-resolution head-related impulse response database for aided and unaided ears

EURASIP Journal on Advances in Signal Processing, 2019
Head-related impulse responses (HRIRs) allow for the creation of virtual acoustic scenes. Since in ideal conditions the human auditory system can localize sounds with a very high degree of accuracy, it is useful to have an HRIR database with high spatial

Head-related transfer function measurements in a compartment fire

The Journal of the Acoustical Society of America, 2022
The Personal Alert Safety System (PASS) is an alarm signal device carried by firefighters to help rescuers locate and extricate downed firefighters. A fire creates temperature gradients and inhomogeneous time-varying temperature, density, and flow fields that modify the acoustic properties of a room.

Binaural Rendering in MPEG Surround

EURASIP Journal on Advances in Signal Processing, 2008
This paper describes novel methods for evoking a multichannel audio experience over stereo headphones. In contrast to the conventional convolution-based approach where, for example, five input channels are filtered using ten head ...

Strong and weak head-related transfer functions: The eHRTF analytical framework [PDF]

JASA Express Letters
This article introduces an analytical framework for modeling head-related transfer functions (HRTFs) from a listener-centered perspective. The distinction between strong (or general) HRTFs, aiming for idealized physical acoustic fidelity, and weak (or ...

Head-Related Transfer Function Interpolation with a Spherical CNN

CoRR, 2023
Head-related transfer functions (HRTFs) are crucial for spatial soundfield reproduction in virtual reality applications. However, obtaining personalized, high-resolution HRTFs is a time-consuming and costly task. Recently, deep learning-based methods showed promise in interpolating high-resolution HRTFs from sparse measurements.

A Spherical Cross-Channel Algorithm for Binaural Sound Localization [PDF]

, 2013
This paper proposes a sound localization algorithm inspired by a cross-channel algorithm first studied by MacDonald et. al in 2008. The original algorithm assumes that the Head Related Transfer Functions (HRTFs) of the robotic head under study are ...

A framework for designing head-related transfer function distance metrics that capture localization perception [PDF]

JASA Express Letters, 2021
Linear comparisons can fail to describe perceptual differences between head-related transfer functions (HRTFs), reducing their utility for perceptual tests, HRTF selection methods, and prediction algorithms.

Efficient Representation of Head-Related Transfer Functions With Combination of Spherical Harmonics and Spherical Wavelets

IEEE Access, 2019
Recently, a modeling method for head-related transfer functions (HRTFs) in the spatial domain is proposed based on spherical wavelets. Because spherical wavelets are local functions on the sphere, HRTF local features can be efficiently represented by ...
