Title: Spatialized Audio Encoding With Configuration Of A Decorrelation Processing Operation

Abstract: The invention relates to a method for encoding audio signals forming in time a succession of frames (t-1, t) of samples, in each of n channels of an ambisonic representation of order higher than 0, the method comprising: - determining, for the current frame to be encoded, the binary value indicating an active or inactive mode of a decorrelation processing operation to be applied to the signals of the current frame and encoding this value into the bitstream; - in the case where the mode is determined to be active, encoding into the bitstream decorrelation-processing information; - generating an output signal to be encoded into the bitstream, depending on the mode determined for the current frame and the mode determined for the preceding frame. The invention also relates to a corresponding decoding method, as well as to encoding and decoding devices implementing the respective encoding and decoding methods.
