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

Speech Intelligibility and HRTF
2019This chapter describes the effects of the HRTF on speech intelligibility. An HRTF causes an interaural phase difference. Under the presence of a masker, the threshold of the target sound is affected by the relationship in the interaural phase difference between the target sound and the masker.

In order to actually measure HRTFs, practical knowledge is also required in addition to understanding the theory of the HRTF. This chapter introduces the author’s knowledge and experience as far as possible, so as to enable the readers to measure HRTFs by themselves.

In order to analyze HRTFs and apply them to acoustic VR systems, signal processing technique is required. This chapter introduces the methods for calculating the ITD and ILD, and extracting the spectral cues. Furthermore, the methods for convolution of the HRIRs and a sound source signal is introduced.

An adaptive filtering method to calculate HRTF
1998 IEEE Second Workshop on Multimedia Signal Processing (Cat. No.98EX175), 2002The objective of virtual 3D sound technology is to convey to the listener an accurate impression of an acoustic environment. This is accomplished by conveying a realistic directional impression of sounds. Most of the successful techniques for doing this are based on the head related transfer function (HRTF).
