Abstract

A method and device for modifying a synthesis of a time domain excitation decoded by a time domain decoder wherein the synthesis of the decoded time domain excitation is classified into one of a number of categories. The decoded time domain excitation is converted into a frequency domain excitation and the frequency domain excitation is modified as a function of the category in which the synthesis of the decoded time domain excitation is classified. The modified frequency domain excitation is converted into a modified time domain excitation and a synthesis filter is supplied with the modified time domain excitation to produce a modified synthesis of the decoded time domain excitation.
