Abstract: A particular method includes determining, based on spectral information corresponding to an audio signal that includes a low-band portion and a high-band portion, that the audio signal includes a component corresponding to an artifact-generating condition. The method also includes filtering the high-band portion of the audio signal and generating an encoded signal. Generating the encoded signal includes determining gain information based on a ratio of a first energy corresponding to filtered high-band output to a second energy corresponding to the low-band portion to reduce an audible effect of the artifact-generating condition.

Abstract: Un método incluye la recepción de un primer valor de un factor de mezcla. El primer valor corresponde a una primera porción de una señal de audio recibida en un codificador de audio. El método incluye la recepción de un segundo valor del factor de mezcla. El segundo valor corresponde a una segunda porción de la señal de audio. El método también incluye la generación de un tercer valor del factor de mezcla, al menos parcialmente con base en el primer valor y el segundo valor y la mezcla de una señal de excitación con ruido modulado con base en el tercer valor. Otro método incluye la determinación de un primer conjunto de valores de frecuencia espectral correspondientes a una señal de audio y la determinación de un segundo conjunto de valores de frecuencia espectral que se aproxima al primer conjunto de valores de frecuencia espectral. Un valor de ganancia correspondiente al menos a una parte de la señal de audio se ajusta con base en la diferencia entre el primer conjunto y el segundo conjunto.

Abstract: A method includes receiving a first value of a mixing factor. The first value corresponds to a first portion of an audio signal received at an audio encoder. The method includes receiving a second value of the mixing factor. The second value corresponds to a second portion of the audio signal. The method also includes generating a third value of the mixing factor at least partially based on the first value and the second value and mixing an excitation signal with modulated noise based on the third value. Another method includes determining a first set of spectral frequency values corresponding to an audio signal and determining a second set of spectral frequency values that approximates the first set of spectral frequency values. A gain value corresponding to at least a portion of the audio signal is adjusted based on a difference between the first set and the second set.
