Abstract  Abstract

A sound encoder and decoder implementing plan of the pitch excitation and code table excitation source energy represented by the parameter transmission of these parameters the required transmission capacity can be reduced to the minimum. These parameters are: a correction factor for long-time energy value a long action when the energy value to match the short energy and one (or more) scale factor such factor (s) shows the excitation source with the relative size of the energy value of the short-time.
