The invention relates to the processing of a signal, the signal comprising a series of samples distributed in consecutive frames. The processing is carried out during the decoding of such a signal in order to replace at least one signal frame lost during decoding, and comprises in particular the following steps: a) searching (S3), in a valid signal available for decoding, for a signal segment having a duration corresponding to a period determined on the basis of said valid signal; b) spectrally analysing the segment (S4), in order to determine spectral components of the segment; and c) synthesising (S6) at least one frame to replace the lost frame, by constructing a synthesis signal from at least one portion of the spectral components. |
