The invention provides methods and devices for stereo encoding and decoding using complex prediction in the frequency domain. ln one embodiment, 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 on the basis of 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. The upmixing can be suspended responsive to control data.
