The TUM-LDV HRTF Database
نویسنده
چکیده
In this article a high resolution database of Head-Related Impulse Responses (HRIRs) and anthropometric parameters for 35 human subjects and two KEMAR manequins is introduced. The HRIRs were computed using Normalized Least Mean Square (NLMS) adaptive filtering. The NLMS method has no audible drawbacks compared to well-established HRIR estimation approaches (MLS and Exponetnial Sweep method) while allowing quasi-infinite azimuth resolution by continuously recording of the excitation signal of a rotating subject (Rothbucher et al., 2013). The obtained LDV database provides HRIRs of six different elevation planes with an azimuth resolution of 1◦ or 0.2◦ and corresponding anthropometric data of 35 human subjects. In this article, the measurement process and the post processing of the HRIRs is described in detail.

A Database of Repeated Head-related Transfer Function Measurements
This paper describes a new HRTF collection, measured at the Music and Audio Research Laboratory (MARL), at NYU. This collection of 40 datasets, consists of repeated HRTF measurements on 4 subjects (10 HRTF sets per subject). Analysis of the data offers an understanding of the expected degree of variation in HRTF sets, which, when supported by subjective evaluation, can provide deeper insight fo...
متن کاملCustomizable Auditory Displays
High-quality virtual audio scene rendering is a must for emerging virtual and augmented reality applications, for perceptual user interfaces, and sonification of data. Personalization of HRTF is necessary in applications where perceptual realism and correct elevation perception is critical. We describe algorithms for creation of virtual auditory spaces by rendering cues that arise from anatomic...
متن کاملHrtf Personalization Using Anthropometric Measurements
Individualized head related transfer functions (HRTFs) are needed for accurate rendering of spatial audio, which is important in many applications. Since these are relatively tedious to acquire, they may not be acceptable for some applications. A number of studies have sought to perform simple customization of the HRTF. We propose and test a strategy for HRTF personalization, based on matching ...
متن کاملMinimum-Phase HRTF Modeling of Pinna Spectral Notches using Group Delay Decomposition
Accurate reconstruction of HRTFs is important in the design and development of high quality 3D binaural sound synthesis systems. Conventionally, minimum phase HRTF model development for reconstruction of HRTFs has been limited to minimum phase-pure delay models which ignore the all pass component of the HRTF. In this paper, a novel method for minimum phase HRTF modeling of Pinna Spectral Notche...
