FIELD: data processing.
SUBSTANCE: invention relates to signal correction, in particular in a decoder, when there is a loss of frames in the signal received at the decoder. Method comprises the steps of: generating a structure of a signal for replacing the lost succession, this structure comprising spectral components determined from valid samples received during decoding before the succession of lost samples; generating a residue between a digital signal available to the decoder, comprising received valid samples, and a signal generated from the spectral components; and extracting blocks from the residue, wherein window weighted blocks are injected into the structure using an overlap-add approach, the injected blocks partially overlapping in time.
EFFECT: improved correction of lost frames.
