P-HRTF: Efficient personalized HRTF computation for high-fidelity spatial sound
2014 IEEE International Symposium on Mixed and Augmented Reality (ISMAR), 2014Accurate rendering of 3D spatial audio for interactive virtual auditory displays requires the use of personalized head-related transfer functions (HRTFs). We present a new approach to compute personalized HRTFs for any individual using a method that combines state-of-the-art image-based 3D modeling with an efficient numerical simulation pipeline.

Differences in human audio localization performance between a HRTF- and a non-HRTF audio system
Proceedings of the 8th Audio Mostly Conference, 2013Spatial audio solutions have been around for a long time in real-time applications, but yielding spatial cues that more closely simulate real life accuracy has been a computational issue, and has often been solved by hardware solutions. This has long been a restriction, but now with more powerful computers this is becoming a lesser and lesser concern ...

Sparse Representation of Hrtfs by Ear Alignment
2019 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2019High quality spatial sound reproduction requires individualized Head Related Transfer Functions (HRTFs) with high spatial resolution. However, measuring such HRTFs requires special and expensive equipment, which may be unavailable for most users. Therefore, reproduction of high resolution HRTFs from sparsely measured HRTFs is of great importance ...

Head Related Transfer Functions (HRTFs) are signal processing models that represent the modifications undergone by the acoustic signal as it interacts with the listener's body. HRTFs can be used to generate binaural sound as they contain all the information about the sound source's location.

As described in Chap. 2 and 3, reproduction of the subject’s own HRTFs provides accurate sound image localization. On the other hand, using the other’s HRTFs causes problems, such as front-back error, rising of a sound image, and inside-of-head localization. This chapter describes in detail past actions for the individualization of HRTFs and the latest

Numerical study of the influence of the torso on the HRTF
IEEE International Conference on Acoustics Speech and Signal Processing, 2002Understanding and simplified modeling of how humans generate cues from the scattering of sounds from their bodies holds the key to many applications in spatial audio. Scattering from the torso is thought to provide cues for source localization. A simplified two-sphere model has been proposed to understand the influence of the torso, and experimental ...

Measuring Anthropometric Data for HRTF Personalization
2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems, 2010Nowadays, multimodal human-like sensing, e.g. vision, hap tics and audition seeks to improve interaction between an operator (human) and a teleoperator (robot) in human centered robotic systems. Head Related Transfer Function (HRTF) based sound rendering techniques, which seek to create a realistic virtual auditory space for listeners, have become a ...

The Estimation of Personalized HRTFs in Individual VAS
2008 Fourth International Conference on Natural Computation, 2008The synthesis of individual virtual auditory system (VAS) is an important and state-of-the-art technology in virtual reality. One of the key factors for individual VAS is to obtain a set of proper head related transfer functions (HRTFs). A personalization method is presented in this paper.

HRTF Representation with Convolutional Auto-encoder
2019The head-related transfer function (HRTF) can be considered as some kind of filter that describes how a sound from an arbitrary spatial direction transfers to the listener’s eardrums. HRTF can be used to synthesize vivid virtual 3D sound that seems to come from any spatial location, which makes it play an important role in the 3D audio technology ...

Reproduction and control of sound image distance are also important elements in three-dimensional acoustics. However, quantitative reproduction and control of sound image distance have not yet been realized. In particular, sound images in the front direction are often localized inside of the head or extremely close to the forehead. In this chapter, the
