METHOD AND APPARATUS FOR DECODING AUDIO SIGNAL

摘要

Method and apparatus for processing audio signals are provided. The method for decoding an audio signal includes extracting a downmix signal and spatial information from a received audio signal and generating a pseudo-surround signal using the downmix signal and the spatial information. The apparatus for decoding an audio signal includes a demultiplexing part extracting a downmix signal and spatial information from a received audio signal and a pseudo- surround decoding part generating a pseudo-surround signal from the downmix signal, using the spatial information.
