Title:
APPARATUS AND METHOD FOR PROCESSING MULTI-CHANNEL AUDIO SIGNAL
Document Type and Number:
WIPO Patent Application WO/2023/210978
Kind Code:
A1
Abstract:
In an embodiment, an audio processing method comprises the steps of: parsing a bitstream so as to obtain at least one substream and additional information; decompressing the at least one substream so as to obtain at least one audio signal of at least one channel group (CG); and demixing the at least one audio signal of the at least one channel group on the basis of the additional information, so as to obtain a multi-channel audio signal, wherein the additional information includes a weight index offset (wIdx_offset) identified on the basis of an energy value of a height channel and an energy value of a surround channel of the multi-channel audio signal.
