Abstract

Se describe un aparato para extraer una senal directa/del ambiente de una senal de mezcla descendente e informacion paramétrica espacial, la senal de mezcla descendente y la informacion paramétrica espacial representan una senal de audio de multiples canales que tiene más canales que la senal de mezcla descendente, donde la informacion paramétrica espacial comprende relaciones intercanal de la senal de audio de multiples canales. El aparato comprende un estimador de la senal directa/del ambiente y un extractor de la senal directa/del ambiente. El estimador de una senal directa/ambiente se configura para estimar una informacion de nivel de una porcion directa y/o una porcion del ambiente de la senal de audio de multiples canales basada en la informacion paramétrica espacial. El extractor de una senal directa/del ambiente está configurado para extraer una porcion de la senal directa y/o una porcion de la senal del ambiente desde una senal de mezcla descendente basada en la informacion de nivel estimada de la porcion directa o de la porcion del ambiente.
