Efficient Individualization of HRTF Using Critical-Band Based Spectral Cues Control

Recently, 3D audio technologies are commonly implemented through headphones. A major problem of the headphone-based 3D audio is in-the-head localization, which occurs due to the inaccurate Head-Related Transfer Function (HRTF). Since the individual measurements of HRTFs are impractical, there have been several researches for HRTF customization. In this paper, we proposed an efficient method of customizing HRTFs. In the proposed method, spectral notches and envelopes are controlled based on a critical-band rate. Thus, the structure of the proposed algorithm is much simpler than that of previous methods, but still effective. The proposed method was evaluated in the problem of externalization, and the results showed that the customized HRTF using proposed method could greatly improve the externalization performance.
