    摘要: A method and apparatus for encoding and decoding an audio signal are provided. The present invention includes receiving an audio signal including a downmix signal and a spatial information signal, if a header is included in the spatial information signal, extracting configuration information from the header, extracting spatial information included in the spatial information signal, and converting the downmix signal to a multi-channel signal using the configuration information and the spatial information. Accordingly, the header can be selectively included in the spatial information signal, thereby 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.

The method of decoding a multi-channel audio signal includes an unpacking unit which extracts a quantized CLD between a pair of channels of a plurality of channels from a bitstream, and an inverse quantization unit which inverse-quantizes the quantized CLD using a quantization table that considers the location properties of the pair of channels.

    摘要: Methods and apparatuses for encoding and decoding a multi-channel audio signal are provided. In the decoding method, a down-mix signal is generated based on an input signal, and spatial information is generated based on the down-mix signal through estimation. Then, a multi-channel audio signal is generated based on the down-mix signal and the spatial information. Therefore, it is possible to compensate for a down-mix signal or generate additional spatial information by using additional information.
