Abstract: An apparatus and method for encoding/decoding a multi-channel signal may be provided. The apparatus of encoding a multi-channel signal may insert information about whether to encode a phase parameter indicating phase information of a plurality of channels, included in the multi-channel signal, in a bitstream of the multi-channel signal. The apparatus of decoding a multi-channel signal may determine whether to up-mix a mono signal using the phase parameter based on the information about whether to encode.

Abstract: A method and apparatus to encode and decode an audio/speech signal is provided. An inputted audio signal or speech signal may be transformed into at least one of a high frequency resolution signal and a high temporal resolution signal. The signal may be encoded by determining an appropriate resolution, the encoded signal may be decoded, and thus the audio signal, the speech signal, and a mixed signal of the audio signal and the speech signal may be processed.

Abstract translation: 可以提供用于对多信道信号进行编码/解码的装置和方法。 编码多声道信号的装置可以在多声道信号的比特流中插入关于是否编码指示包括在多声道信号中的多个声道的相位信息的相位参数的信息。 解码多声道信号的装置可以基于关于是否编码的信息，使用相位参数来确定是否对单声道信号进行混合。
