Abstract  Abstract

In one embodiment, a signal processing method includes encoding a low frequency portion of a speech signal with at least an encoded narrowband excitation signal and a plurality of narrowband filter parameters, and generating a highband excitation signal based on the narrowband excitation signal. Steps. The narrowband excitation signal is based on the encoded narrowband excitation signal. The method also includes encoding the high frequency portion of the speech signal into at least a plurality of highband filter parameters in accordance with at least the highband excitation signal. The encoded narrowband excitation signal includes a time distortion, and the method includes applying a time shift to the high frequency portion based on the information about the time distortion.
