摘　　要：从3D音频技术的还音原理出发,以现存普遍的技术为例,对3D音频技术的还音原理进行了研究和分类,发现3D音频技术的还音原理分为三类:基于声道及声道群的3D音频技术、基于波场合成(WFS)的3D音频技术、基于人头相关传递函数(HRTF)的3D音频技术.本文对目前多声道、多维度的新兴音频技术市场和名目繁多的技术指导进行了梳理,给从业者和相关受众提供了一种选择判断的思路.At present,multi-channel and multi-dimensional emerging audio technologies emerge in endlessly,and various kinds of technical names inevitably confuse the audience and practitioners. This paper starts from the sound playback principle of 3D audio technology,and takes today’s more common technologies as an example to study and make classification and induction. According to the principle of sound reproduction,it is divided into three categories:3D audio technology based on channels and channel groups;3D audio technology based on wave field synthesis(WFS);3D audio technology based on human head related transfer function(HRTF).
