Abstract

Un procesador de señal de audio para proporcionar canales de señal ambiental con base en una señal de audio de entrada, está configurado para extraer una señal ambiental con base en la señal de audio de entrada. El procesador de señal está configurado para distribuir la señal ambiental a una pluralidad de canales de señal ambiental dependiendo de las posiciones o direcciones de las fuentes de sonido dentro de la señal de audio de entrada, en donde un número de canales de señal ambiental es más grande que un número de canales de la señal de audio de entrada.
