    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.

    摘要: The present invention relates to a method and apparatus for encoding and decoding object- based audio signals. This audio decoding method includes extracting a first audio signal and a first audio parameter in which a music object are encoded on a channel basis and a second audio signal and a second audio parameter in which a vocal object are encoded on an object basis, from an audio signal, generating a third audio signal by employing at least one of the first and second audio signals, and generating a multi-channel audio signal by employing at least one of the first and second audio parameters and the third audio signal. Accordingly, the amount of calculation in encoding and decoding processes and the size of a bitstream that is encoded can be reduced efficiently.

    摘要: A method for processing an audio signal, comprising the steps of extracting an ancillary signal for generating the audio signal and an extension signal included in the ancillary signal from a received bit stream, reading length information for the extension signal, skipping decoding of the extension signal or not using a result of the decoding based on the length information, and generating the audio signal using the ancillary signal. Accordingly, in case of processing the audio signal by the present invention, it is able to reduce a corresponding load of operation to enable efficient processing and enhance a sound quality.

    摘要: An encoding method and apparatus and a decoding method and apparatus are provided. The decoding method includes extracting a compatible down-mix signal optimized for a first multi-channel decoder from the input bitstream, converting the compatible down-mix signal to be optimized for a second multi-channel signal by performing a compatibility processing operation on the compatible down-mix signal, and generating a three-dimensional (3D) down-mix signal by performing a 3D rendering operation on the converted down-mix signal. Accordingly, it is possible to efficiently encode multi-channel signals with 3D effects and to adaptively restore and reproduce audio signals with optimum sound quality according to the characteristics of an audio reproduction environment.
