METHODS AND EQUIPMENT FOR CODING MULTI-CHANNEL AUDIO SIGNALS, COMMUNICATION EQUIPMENT, AND COMPUTER-READABLE STORAGE MEDIA

Abstract

The invention relates to a method and apparatus for encoding multi-channel audio signals, a communication apparatus and a computer-readable storage medium.* The method for encoding multi-channel audio signals (300) consists of the following steps: the first audio frame to be encoded (301); pairing at least five channel signals in the first pairing method to obtain the first set of channel pairs (302); summing the first correlation values ​​of the first set of channel pairs, in which each channel pair has one correlation value (303); pairing at least five channel signals in the second pairing method to obtain the second set of channel pairs (304); summing the second correlation values ​​of the second set of channel pairs (305); determining the target pairing of at least five channel signals based on the sum of the first correlation values ​​and the sum of the second correlation values ​​(306);and to encode at least five channel signals based on a set of channel pairs corresponding to the target pairing, where this target pairing is either the first or second pairing (311). Multichannel audio signal encoding methods and equipment (300) make audio frame encoding methods more versatile and efficient.;
