Abstract
Un codificador para codificar una señal de audio en un flujo de datos que comprende un predictor, un factorizador, un transformador y una etapa de cuantización y codificación. El predictor está configurado para analizar la señal de audio para obtener coeficientes de predicción que describan un análogo espectral de la señal de audio o una frecuencia fundamental de la señal de audio y someter la señal de audio a una función de filtro de análisis dependiente de los coeficientes de predicción para producir una señal residual de la señal de audio. El factorizador está configurado para aplicar una factorización de matriz sobre una matriz de autocorrelación o covarianza de la función de filtro de síntesis definida por los coeficientes de predicción para obtener matrices factorizadas. El transformador está configurado para transformar la señal residual con base en las matrices factorizadas para obtener una señal residual transformada. La etapa de cuantización y descodificación está configurada para cuantizar la señal residual transformada para obtener una señal residual transformada, cuantizada o una señal residual transformada, cuantizada codificada.
