摘要
A signal processing device, media, and method are provided, where a signal comprises a succession of samples distributed in successive frames. The processing is implemented during decoding of such a signal in order to replace at least one signal frame lost in decoding, and comprising in particular: a) searching, in a valid signal available to the decoder, for a signal segment of length corresponding to a period set as a function of the valid signal; b) analyzing a spectrum of the segment in order to determine spectral components of the segment; and c) synthesizing at least one replacement frame for the lost frame by construction of a synthesized signal from at least a portion of the spectral components.
