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 a first preliminary time lag (ppfe1) based upon examining a predetermined number (K) of samples of another segment of the decoded signal; determining a scaling factor (ptfe) associated with the examined number (K) of samples when the first preliminary time lag (ppfe1) is determined; and extrapolating one or more replacement frames based upon the first preliminary time lag (ppfe1) and the scaling factor (ptfe).
