Abstract: A method for decoding an audio signal, receiving a downmix signal having at least one independent object and a background object downmixed therein receiving object information and enhanced object information, wherein the object information includes at least one of level information and correlation information between the independent object and the background object, wherein the enhanced object information includes a residual signal extracting the at least one independent object and the background object from the downmix signal using the object information and the enhanced object information receiving mix information from a user, the mix information being usable to control gain or panning of the independent object or the background object generating downmix processing information using at least one of the object information and enhanced object information processing at least one independent object and the background object using at least one of the downmix processing information and the mix information.

Abstract translation: 一种用于对音频信号进行解码的方法，接收具有至少一个独立对象的下混合信号和在其中下混合的接收对象信息和增强对象信息的背景对象，其中所述对象信息包括所述独立对象之间的电平信息和相关信息中的至少一个 背景物体，其中所述增强对象信息包括使用来自用户的对象信息和所述增强对象信息接收混合信息从所述下混合信号中提取所述至少一个独立对象和所述背景对象的残差信号，所述混合信息可用 使用至少一个独立对象和所述背景对象使用所述下混合处理信息和所述背景对象中的至少一个来控​​制所述独立对象或背景对象的增益或平移，所述独立对象或所述背景对象使用所述对象信息和所述增强对象信息中的至少一个来生成下混合处理信息， 混合信息。
