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 6):
An audio decoding method performed by a processor, comprising:\n decoding an encoded intermediate channel signal related to a layout of a speaker system, and a metadata, extracting a background sound, an object sound from the decoded intermediate channel signal, rendering the object sound and the background sound based on the 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.
