Abstract  Abstract

The invention claims a specific method that includes voiced classification for determining the input signal at the device. the input signal corresponding to the audio signal. The method also includes based on the voiced classification control amount represented by the envelope of the input signal. The method further includes based on the envelope of the controlled amount of modulated white noise signal. The method also comprises based on the modulated white noise signal to generate a high band excitation signal.

A particular method includes determining at a device a voicing classification of an input signal. The input signal corresponds to an audio signal. The method also includes controlling an amount of an envelope of a representation of the input signal based on the voicing classification. The method further includes modulating a white noise signal based on the controlled amount of the envelope. The method also includes generating a high band excitation signal based on the modulated white noise signal.
