Abstract  Abstract

SUMMARY An improved method and apparatus for digitally encoding a wideband signal, particularly, but not limited to, a speech signal for transmission or storage and synthesis of the wideband acoustic signal. This new method and apparatus for efficient modeling of the harmonic structure of the speech spectrum uses some form of low-pass filter applied to the pitch code vector, and uses higher predictive gain (ie, minimum pitch). The low pass filter that obtains the prediction error) is selected and the pitch codebook parameters associated with it are sent out.
