Abstract:
A method and apparatus for encoding and decoding an audio signal are provided. The present invention includes receiving an audio signal including an audio descriptor, recognizing that the audio signal includes a downmix signal and a spatial information signal using the audio descriptor, and converting the downmix signal to a multi-channel signal using the spatial information signal, wherein the spatial information signal includes a header each a preset temporal or spatial interval, and the spatial information signal includes a header each a preset temporal or spatial interval thereby the header can be selectively included in the spatial information signal and if the header is plurally included in the spatial information signal, it is able to decode spatial information in case of reproducing the audio signal from a random point.
