Abstract
Un aparato para mezclar hacia arriba una senal de audio mezclada hacia abajo en una senal de audio mezclada hacia arriba describiendo una pluralidad de canales de audio mezclados hacia arriba comprende un aplicador de parámetros configurado para aplicar parámetros de mezclado hacia arriba para mezclar hacia arriba la senal de audio mezclada hacia abajo para obtener la senal de audio mezclada hacia arriba. El aplicador de parámetros está configurado para aplicar un corrimiento de fase a la senal de audio mezclada hacia abajo para obtener una version de fase corrida de la senal de audio mezclada hacia abajo, mientras que deja una senal decorrelacionada no modificada por el corrimiento de fase. El aplicador de parámetros además está configurado para combinar la version de fase corrida de la senal de audio mezclada hacia abajo para obtener la senal de audio mezclada hacia arriba.
