Abstract:
1. A method for synthesizing a digital audio signal, represented by successive blocks of samples, in which on receiving such a signal, in order to replace at least one invalid block, a replacement block is generated from samples of at least one valid block preceding the invalid block, the method comprising the following steps: a) determining a repetition period in at least one valid block, and b) copying the samples of the repetition period into at least one replacement block, wherein: in step a), a last repetition period is determined in at least one valid block immediately preceding an invalid block, in step b), the samples of said last repetition period are corrected according to samples of a previous repetition period preceding said last repetition period, in order to limit the amplitude of any transitory signal in said last repetition period, and the samples thus corrected are copied into said replacement block.
