FIELD: data processing.
SUBSTANCE: invention relates to signal processing. Method of processing audio data includes receiving from a bit stream audio data, corresponding to a row of audio channels, application of decorrelation process to some of audio data, wherein decorrelation process involves using a decorrelation algorithm, active completely on real-valued coefficients.
EFFECT: reduced complexity of coding and decoding algorithms owing to decorrelation of only real-valued coefficients.
