Abstract
Un codificador para la codificación de una señal de audio comprende un analizador configurado para el análisis de la señal de audio y para la determinación de los coeficientes de predicción de análisis a partir de la señal de audio. El codificador adicionalmente comprende un conversor configurado para la derivación de coeficientes de predicción convertidos a partir de los coeficientes de predicción de análisis, una memoria configurada para el almacenamiento de una cantidad de valores de corrección y una calculadora. La calculadora comprende un procesador configurado para el procesamiento de los coeficientes de predicción convertidos a fin de obtener factores de ponderación espectral. La calculadora adicionalmente comprende una combinadora configurada para combinar los factores de ponderación espectral y la cantidad de valores de corrección a fin de obtener factores de ponderación corregidos. Un cuantificador de la calculadora está configurado para cuantificar los coeficientes de predicción convertidos usando los factores de ponderación corregidos a fin de obtener una representación cuantificada de los coeficientes de predicción convertidos. El codificador comprende un formador de corriente de bits configurado para formar una señal de salida sobre la base de la representación cuantificada de los coeficientes de predicción convertidos y sobre la base de la señal de audio.An encoder for encoding an audio signal comprises an analyzer configured for the analysis of the audio signal and for the determination of the analysis prediction coefficients from the audio signal. The encoder additionally comprises a converter configured for the derivation of prediction coefficients converted from the analysis prediction coefficients, a memory configured for the storage of a number of correction values and a calculator. The calculator comprises a processor configured for processing the converted prediction coefficients in order to obtain spectral weighting factors. The calculator additionally comprises a combiner configured to combine the spectral weighting factors and the amount of correction values in order to obtain corrected weighting factors. A calculator quantifier is configured to quantify the converted prediction coefficients using the corrected weighting factors in order to obtain a quantified representation of the converted prediction coefficients. The encoder comprises a bit stream former configured to form an output signal based on the quantized representation of the converted prediction coefficients and on the basis of the audio signal.
