Numerically simulated Head-Related Transfer Functions (HRTFs) provide an attractive alternative to acoustic measurement, removing the need for anechoic facilities and dedicated measurement equipment. However, their perceptual fidelity remains limited compared to gold-standard acoustic measurements, with residual errors in interaural time differences (ITDs), interaural level differences (ILDs)...

Head-related transfer functions (HRTFs) describe how the human head, torso, and pinnae filter sound arriving from different directions. They are unique to each listener and are an important part of binaural rendering, spatial audio, and virtual reality systems. HRTF research involves not only acoustic analysis but also the management of Spatially Oriented Format for Acoustics (SOFA) files,...

The exponential sine sweep (ESS) technique became the common approach for measuring head-related transfer functions (HRTFs) since it allows separating the loudspeaker’s distortion from the HRTF by temporal windowing. This, however, fails with overlapping excitation signals. This work assesses the signal-to-noise ratio (SNR) benefit from nonlinear harmonic prediction and subtraction. The...

Individualized head-related transfer functions(HRTFs) are an essential tool for accurate spatialaudio reproduction, but traditional measurementprocedures are time-consuming and require specializedlaboratory equipment. Numerical approaches enablethe computation of individualized HRTFs from 3Dmodels of the torso, head, and pinnae. Althoughaccurate 3D models present a challenge in itself,recent...

The 2024 Listener Acoustic Personalisation (LAP24) challenge benchmarked the spatial upsampling (interpolation) of head-related transfer functions (HRTFs). Seven teams submitted HRTFs that were upsampled from four sparse grids containing between three and one hundred HRTF positions. The submissions included six deep learning-based approaches and one algorithmic approach. They were evaluated...

With the recent surge in augmented reality (AR) applications, devices such as head-mounted displays (HMDs) and headphones are increasingly used as multimodal interfaces that combine visual and auditory information to create immersive experiences. However, to date, studies have focused on evaluating the impact of head-worn devices (HWDs) on head-related transfer functions considering either...
