19. An automobile audio system for an automobile, said automobile audio system comprising:
one or more external microphones configured to record external sound and establish one or more recorded audio signals;
an audio processing unit configured to determine a relative directionality of one or more external sound sources of said recorded external sound with respect to at least one occupant, and further configured to establish at least one directionality encoded audio signal by applying at least one frequency dependent directionality filter to said one or more recorded audio signals, wherein said at least one frequency dependent directionality filter is based on said determined relative directionality of said one or more external sound sources, thereby encoding said relative directionality into said at least one directionality encoded audio signal; and
one or more internal loudspeakers configured to reproduce a representation of said external sound based on said at least one directionality encoded audio signal.
