Abstract: Provided are a method of separating a second audio from a first audio by using one or more artificial neural networks, and an electronic device for performing the method. The method includes extracting a plurality of pieces of first feature data from target information related to the second audio, generating second feature data by applying a plurality of feature separation vectors corresponding to types of the target information, to the plurality of pieces of first feature data, and separating the second audio from the first audio based on the second feature data.

Abstract: Disclosed are an audio processing apparatus and method including obtaining at least one substream and additional information by parsing a bitstream, obtaining at least one audio signal of at least one channel group (CG) by decompressing the at least one substream, and obtaining a multi-channel audio signal by de-mixing the at least one audio signal of the at least one CG, based on the additional information. The additional information includes a weight index offset identified based on an energy value of a height channel of the multi-channel audio signal and an energy value of a surround channel of the multi-channel audio signal.

Abstract: An apparatus for processing audio includes at least one processor configured to obtain a down-mixed audio signal from a bitstream, to obtain down-mixing-related information from the bitstream, to de-mix the down-mixing-related information by using down-mixing-related information, and to reconstruct an audio signal including at least one frame based on the de-mixed audio signal. The down-mixing-related information is information generated in units of frames by using an audio scene type.
