Abstract
A method for encoding audio signals forming in time a succession of frames of samples, in each of n channels of an ambisonic representation of order higher than 0. The method includes: 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. A corresponding decoding method is provided, as well as encoding and decoding devices implementing the respective encoding and decoding methods.
