基于空间对象的虚拟会议音频重建

Virtual Conference Audio Reconstruction Based on Spatial Object

提出了一种基于空间音频对象的虚拟会议音频重建模型,以提高虚拟会议合成音频的真实感。首先,根据虚拟会议的特点给出了合成会议音频的方法;然后,根据空间音频对象编码的原理,使用空间音频参数双耳声级差针对每个听者重建其空间声场。

A virtual conference audio reconstruction model based on spatial audio object is proposed. The aim of the model is to enhance the realistic experience of virtual conference. Firstly, the conference audio synthesis method is given according to the principle of the virtual conference. Then the spatial audio parameter ILD （Interaural Level Difference） is used to reconstruct the spatial sound field for each listener based on the theory of spatial audio object coding.
