Abstract: A method of and apparatus for coding wide-band audio signals are provided, wherein the band of the signal to be coded is split into two sub-bands; the sign als in each sub-band are coded in coders (CD1, CD2) operating according to analysis-by-synthesis techniques and exploiting short-term and long-term correlations in the speech signal. Two embodiments of such coders are described, the first utilizing a multi-pulse excitation and the other the CELP coding technique.
