Abstract: 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.

Abstract: Un procedimiento para generación de señal de excitación de banda alta que comprende: determinar, en un dispositivo, una clasificación de sonoridad de una señal de entrada, en el que la señal de entrada corresponde a una señal de audio; controlar una envolvente de una señal de excitación de la señal de entrada basándose en la clasificación de sonoridad, en el que el intervalo de frecuencia de la envolvente se controla basándose en una frecuencia de corte de un filtro de paso bajo aplicado a la señal de excitación de la señal de entrada; modular una señal de ruido blanco basándose en la envolvente controlada; y generar una señal de excitación de banda alta basándose en la señal de ruido blanco modulada.

Abstract: A method includes extracting a voicing classification parameter of an audio signal and determining a filter coefficient of a low pass filter based on the voicing classification parameter. The method also includes filtering a low-band portion of the audio signal to generate a low-band audio signal and controlling an amplitude of a temporal envelope of the low-band audio signal based on the filter coefficient. The method also includes modulating a white noise signal based on the amplitude of the temporal envelope to generate a modulated white noise signal and scaling the modulated white noise signal based on a noise gain to generate a scaled modulated white noise signal. The method also includes mixing a scaled version of the low-band audio signal with the scaled modulated white noise signal to generate a high-band excitation signal that is used to generate a decoded version of the audio signal.

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)
