METHOD AND APPARATUS FOR ENCODING MULTI-CHANNEL AUDIO SIGNAL AND METHOD AND APPARATUS FOR DECODING MULTI-CHANNEL AUDIO SIGNAL |
摘要 |
A method and apparatus which encode multi-channel audio signals and a method and apparatus which decode multi-channel audio signals. When encoding, a downmixed audio signal, first additional information for restoring multi-channel audio signals from the downmixed audio signal, and second additional information representing characteristics of a residual signal are multiplexed. When decoding, restored multi-channel audio signals having a predetermined phase difference are combined using the second additional information, and an audio signal of each channel is corrected, in order to improve quality of the restored audio signals. |
