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.
