8. The method of claim 1 , wherein said harmonically-filtered residual signal is further processed to remove periodic energy envelope modulation by modeling using a sum of multiple instances of a periodic function at arbitrary frequencies taking into account the time-domain energy envelope signal estimate with imposed periodicity before analysis by synthesis coding.
