Abstract  Abstract

In one embodiment, a method for generating a highband excitation signal comprises: generating a spectral extension signal by extending the spectrum of the signal based on the encoded lowband excitation signal; And performing semi-lean filtering of the signal based on the encoded low band excitation signal. In this method, the highband excitation signal is based on the spectral extension signal, and the highband excitation signal is based on the result of performing the semi-lean filtering.

Highband excitation signal, lowband excitation signal, semi-lean filter
