Abstract:
An audio encoding apparatus and method that encodes hybrid contents including an object sound, a background sound, and metadata, and an audio decoding apparatus and method that decodes the encoded hybrid contents are provided. The audio encoding apparatus may include a mixing unit to generate an intermediate channel signal by mixing a background sound and an object sound, a matrix information encoding unit to encode matrix information used for the mixing, an audio encoding unit to encode the intermediate channel signal, and a metadata encoding unit to encode metadata including control information of the object sound.

Claim (Index 1):
An audio decoding method performed by a processor, comprising:\n decoding an encoded intermediate channel signal included in a bitstream, and an object sound or a background sound to be used for unmixing of the decoded intermediate channel signal; decoding matrix information used for the unmixing the decoded intermediate channel signal; unmixing the decoded intermediate channel signal using the matrix information and outputs the object sound and the background sound; and decoding metadata including control information of the object sound and outputs the decoded metadata, wherein the number of channels of the intermediate channel signal has the same number of channels as the number of channels of the background sound, wherein the metadata is used to render to a layout of a speaker system based on audio reproduction environments.
