FIELD: radio engineering, communication.SUBSTANCE: invention relates to means of stereo encoding and decoding using complex prediction in the frequency domain. A decoding method for obtaining an output stereo signal from an input stereo signal encoded by complex prediction coding and comprising first frequency-domain representations of two input channels, comprises the upmixing steps of: (i) computing a second frequency-domain representation of a first input channel; and (ii) computing an output channel based on the first and second frequency-domain representations of the first input channel, the first frequency-domain representation of the second input channel and a complex prediction coefficient.EFFECT: high speed of encoding in the range of high bit transfer rates.14 cl, 19 dwg, 1 tbl |
