Abstract
Una eficacia de codificación de la codificación de coeficientes espectrales de un espectro de una señal de audio se incrementa por la codificación/decodificación de un coeficiente espectral actualmente a codificar/decodificar por codificación/decodificació n por entropía y, al hacerlo, la realización de codificación/decodificación por entropía dependiendo, en una manera adaptativa al contexto, de un coeficiente espectral previamente codificado/decodificado, mientras se ajusta una distancia espectral relativa entre el coeficiente espectral previamente codificado/decodificado y el coeficiente espectral actualmente codificado/decodificado en función de una información relativa a una forma del espectro. La información relativa a la forma del espectro puede comprender una medida de un tono o periodicidad de la señal de audio, una medida de una distancia inter-armónica del espectro de la señal de audio y/o ubicaciones relativas de formantes y/o valles de una envolvente espectral del espectro, y sobre la base de este conocimiento, la zona espectral que es explotada con el fin de formar el contexto de la coeficientes espectrales actualmente a codificar/decodificar se pueden adaptar a la forma así determinada del espectro, mejorando así la eficiencia de la codificación por entropía.
