Abstract
Un aparato para mezclar en forma ascendente una senal de audio con mezcla descendente que describe uno o más canales de audio de mezcla descendente en una senal de audio mezclada en forma ascendente que describe una pluralidad de canales de audio mezclados en forma ascendente comprende un mezclador ascendente y un determinador de parámetro. El mezclador ascendente está configurado para aplicar parámetros de mezcla ascendente temporalmente variables para mezclar en forma ascendente la senal de audio con mezcla descendente para obtener la senal de audio mezclada en forma ascendente, donde los parámetros de mezcla ascendente temporalmente variables comprenden valores de fase suavizados temporalmente variables. El determinador de parámetro está configurado para obtener uno o más parámetros de mezcla ascendente temporalmente suavizados para ser utilizados por el mezclador ascendente teniendo en cuenta una informacion de entrada del parámetro cuantizada. El determinador de parámetro está configurado para combinar una version ajustada a escala de un valor de fase suavizado previo con una version ajustada a escala de una informacion de fase de entrada utilizando un algoritmo de limitacion de cambio de fase, para determinar un valor de fase suavizado actual teniendo en cuenta el valor de fase suavizado previo y la informacion de fase de entrada.
