HRTF Estimation using a Score-based Prior
IEEE International Conference on Acoustics, Speech, and Signal ProcessingWe present a head-related transfer function (HRTF) estimation method which relies on a data-driven prior given by a score-based diffusion model. The HRTF is estimated in reverberant environments using natural excitation signals, e.g. human speech.

Exploring redundancy of HRTFs for fast training DNN-based HRTF personalization
2018 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2018A deep neural network (DNN) is constructed to predict the magnitude responses of the head-related transfer functions (HRTFs) of users for a specific direction and a specific ear. Using the CIPIC HRTF database (including 25 azimuth angles and 50 elevation angles for both ears), we trained 2500 DNNs to predict magnitude responses of all HRTFs of a user ...

HRTF modeling for efficient auralization
2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004This paper presents a computationally efficient auralization method, which combines a wavelet-based model for head related transfer functions (HRTFs) with the grouping of such functions for close directions. The proposed method results in a significant reduction of the processing time of the auralization process, by modeling the HRTFs using wavelet ...

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

Efficient aliasing-free HRTF representation
The Journal of the Acoustical Society of America, 2017Previous studies have shown that individualized head related transfer functions (HRTFs) provide improved localization performance compared to generic HRTF filters, and are therefore considered preferable for binaural sound reproduction. However, individualized HRTFs typically require a large number of measurements, which may extend to several hours ...

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 ...

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.

Interpolating HRTF for auditory virtual reality
The Journal of the Acoustical Society of America, 1996Two (linear and nonlinear) interpolation methods of the head-related transfer function (HRTF) are exploited in order to realize virtual auditory localization. In both methods, HRTFs of the left and right ears are represented by a delay time and a common impulse response, where delay time is determined so that the cross correlation of two HRTFs takes ...

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

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.
