    • Provided is a multi-channel audio decoding method and apparatus therefor, the method involving decoding filter bank coefficients of a plurality of bands from a bitstream having a predetermined format; performing frequency transformation on the decoded filter bank coefficients of the plurality of bands, with respect to each of the plurality of bands; compensating for a phase of each of the plurality of bands according to a predetermined phase compensation value, and serially band-synthesizing the frequency-transformed coefficients of each of the plurality of phase-compensated bands on a frequency domain; and decoding a multi-channel audio signal from the band-synthesized frequency-transformed coefficients.
    • 提供一种多声道音频解码方法及其装置,该方法包括从具有预定格式的比特流中解码多个频带的滤波器组系数; 对所述多个频带的解码滤波器组系数进行相对于所述多个频带中的每一个的频率变换; 根据预定的相位补偿值补偿多个频带中的每一个的相位,并且对频域上的多个相位补偿频带中的每一个的频率变换系数进行串行频带合成; 以及从频带合成的频率变换系数中解码多声道音频信号。
