MULTIPLE CHANNEL AUDIO SIGNAL ENCODER MODE DETERMINER

摘要

It is inter alia disclosed a method comprising: determining an indication of similarity between a first audio frame of a multiple channel input audio signal and a second audio frame of the multiple channel input audio signal; and determining a coding mode for a multiple channel audio spatial encoder dependent on each of: data indicating a coding mode of a mono audio encoder for the first audio frame of the multiple channel input audio signal; a coding mode of the multichannel spatial audio encoder for the first audio frame of the multiple channel input audio signal; and the indication of similarity.
