<p>The invention relates to the coding/decoding of a digital signal, consisting of successive blocks of samples, the coding being of the transform with overlap type and comprising, upon analysis, the application of a weighting window to two blocks of M successive samples. In particular, this weighting window is asymmetric and comprises four distinct portions extending successively over the two aforesaid blocks, with: a first portion (wl), increasing over a first interval of samples, a second portion (w2), constant at a value of 1 over a second interval, a third portion (w3), decreasing over a third interval, and a fourth portion (w4), constant at a value of 0 over a fourth interval.</p> |
