    Abstract: An audio decoding method and apparatus and an audio encoding method and apparatus which can efficiently process object-based audio signals are provided. The audio decoding method includes receiving a downmix signal and object-based side information, the downmix signal comprising at least two downmix channel signals; extracting gain information from the object-based side information and generating modification information for modifying the downmix channel signals on a channel-by-channel basis based on the gain information; and modifying the downmix channel signals by applying the modification information to the downmix channel signals.

    Abstract translation: 提供了可以有效地处理基于对象的音频信号的音频解码方法和装置以及音频编码方法和装置。 音频解码方法包括:接收下混合信号和基于对象的侧信息,所述降混信号包括至少两个下混通道信号; 从所述基于对象的侧信息提取增益信息,并且基于所述增益信息生成用于修改所述下混频道信号的修改信息; 以及通过将所述修改信息应用于所述下混通道信号来修改所述下混通道信号。

    Abstract: Provided are an audio encoding method and apparatus and an audio decoding method and apparatus in which audio signals can be encoded or decoded so that sound images can be localized at any desired position for each object audio signal. The audio decoding method generating a third downmix signal by combining a first downmix signal extracted from a first audio signal and a second downmix signal extracted from a second audio signal; generating third object-based side information by combining first object-based side information extracted from the first audio signal and second object-based side information extracted from the second audio signal; converting the third object-based side information into channel-based side information; and generating a multi-channel audio signal using the third downmix signal and the channel-based side information.

    Abstract translation: 提供了一种音频编码方法和装置以及音频解码方法和装置,其中可以对音频信号进行编码或解码,使得声音图像可以被定位在每个对象音频信号的任何期望位置。 音频解码方法,通过组合从第一音频信号提取的第一下混合信号和从第二音频信号提取的第二下混频信号来产生第三降混信号; 通过组合从第一音频信号提取的第一基于对象的侧信息和从第二音频信号提取的第二基于对象的侧信息来生成第三对象侧边信息; 将所述第三对象侧信息转换为基于信道的侧信息; 以及使用第三下混信号和基于频道的侧信息来生成多声道音频信号。
