AES专论-双耳技术(三):双耳信号合成中HRTF的个体化
|
摘要
在简述双耳信号合成中HRTF个体化的重放效果和非个体化可能产生的影响后,介绍了几种个体化定制的处理方法,并对HRTF个体化建模有效性以及虚拟听觉空间质量的评价进行了介绍。
After describing the reproduction performance of individualized synthesis and the divergence from this result in case of non-individualized synthesis,the various methods for individual customization of HRTF are introduced. Furthermore,the aspects,concerning assessment of the validity of HRTF individualization as well as the quality of virtual auditory space,are discussed.
