FIELD: computer engineering.
SUBSTANCE: processing audio data. The technical result is achieved by applying the first set of scaling parameters to the first channel of a multi-channel audio signal and applying the second set of scaling parameters to the second channel of a multi-channel audio signal and extracting multi-channel audio data; and using the multi-channel audio data and information regarding the first group of jointly coded scaling parameters and information regarding the second group of jointly coded scaling parameters to obtain a coded multi-channel audio signal.
EFFECT: reducing the bit rate of encoding the base signal to improve the overall perceptual quality of a stereo or multi-channel signal.
