    • Provided are an apparatus and method for coding and decoding a multi object audio signal with multi channel. The apparatus includes: a multi channel encoding means for down-mixing an audio signal including a plurality of channels, generating a spatial cue for the audio signal including the plurality of channels, and generating first rendering information including the generated spatial cue; and a multi object encoding unit for down-mixing an audio signal including a plurality of objects, which includes the down-mixed signal from the multi channel encoding unit, generating a spatial cue for the audio signal including the plurality of objects, and generating second rendering information including the generated spatial cue, wherein the multichannel encoding unit generates a spatial cue for the audio signal including the plurality of objects regardless of a Coder-DECoder (CODEC) scheme the limits the multi channel encoding unit.
    • 提供了一种用于对具有多信道的多对象音频信号进行编码和解码的装置和方法。 该装置包括:多通道编码装置,用于对包括多个通道的音频信号进行下变频混合,产生包括多个通道的音频信号的空间提示,以及生成包括产生的空间提示的第一渲染信息; 以及多对象编码单元,用于对包括来自所述多通道编码单元的所述下混合信号的包括多个对象的音频信号进行下混频,以产生包括所述多个对象的音频信号的空间提示,并且产生第二 包括生成的空间提示的渲染信息,其中多通道编码单元生成包括多个对象的音频信号的空间提示,而不管编码器 - 解码器(CODEC)方案如何限制多频道编码单元。
