摘要
本文在对三维声行业标准《三维声编解码及渲染》(Audio Vivid)深入研究的基础上,分析三维声编解码和渲染端到端技术框架,介绍基于神经网络的通用码率音频编码、元数据编码、扬声器渲染和双耳渲染等关键技术,给出卡塔尔世界杯期间Audio Vivid标准端到端技术试验情况,为Audio Vivid标准应用部署提供技术参考。
Based on the comprehensive study of the standard“3D audio coding and rendering”(Audio Vivid),this paper analyzes the end-to-end technical framework of 3D audio coding and rendering.Key technologies such as general bitrate audio coding based on neural network,metadata coding,speaker rendering and binaural rendering are presented,and the end-to-end technical trials of the Audio Vivid standard during the Qatar World Cup are given,providing technical reference for the deployment of the Audio Vivid standard application.
