本文介绍了空间声音的表示使用有限数量的HRTF。HRTF是用于为沉浸式音频系统生成3D声音的重要功能。然而，HRTF不仅是声音到达方向的函数，而且由于收听者的个体差异而变化。因此，期望使用几个HRTF数据记录来生成各个HRTF。本报告研究了从数据库和有限数量的测量的个体HRTF生成个体受试者的HRTF的可能性。在生成的HRTF中观察到的估计误差可以通过信号偏差比（SDR）来评估。使用4个受试者的HRTF的本示例示出了水平面中的各个HRTF可以被合成为具有大于约6dB的SDR。HRTF的子带分析/合成正在研究中。
This article describes the representation of spatial sound using a limited number of HRTFs. The HRTFs are significant functions for generating 3D sounds for immersive audio systems. The HRTFs, however, are not only functions of sound arrival directions but are also variable due to listeners' individual differences. Thus generation of the individual HRTFs using a few HRTF data records is desired. This report investigates a possibility in generating HRTFs for an individual subject from a database and a limited number of measured individual HRTFs. The estimation errors which are observed in the generated HRTFs can be evaluated by the signal to deviation ratio (SDR). A present example using 4 subjects' HRTFs shows that individual HRTFs in the horizontal plane can be synthesised with SDR greater than about 6 dB. Sub-band analysis/synthesis for the HRTFs is under study.
