1. A method of synthesizing a number of corrupted frames output from a decoder including one or more predictive filters, the corrupted frames being representative of one segment of a decoded signal (sq(n)) output from the decoder, the method comprising: determining, using at least one processor, a first preliminary time lag (ppfe 1 ) based upon examining a predetermined number (K) of samples of another segment of the decoded signal; determining, using the at least one processor, a scaling factor (ptfe) associated with the examined number (K) of samples, the scaling factor (ptfe) only being a function of (i) the first preliminary time lag (ppfe 1 ) and (ii) the decoded signal (sq(n)); and extrapolating, using the at least one processor, a first replacement frame based upon the first preliminary time lag (ppfe 1 ) and the scaling factor (ptfe).
