    Abstract: A particular method includes determining (802), at a device, a voicing classification (180) of an input signal (130). The input signal corresponds to an audio signal. The method also includes controlling (804) an amount of an envelope of a representation of the input signal based on the voicing classification. The method further includes modulating (806) a white noise signal (156) based on the controlled amount of the envelope. The method also includes generating (808) a high band excitation signal (186) based on the modulated white noise signal (184). (Figure 1)
