A computer-implemented method performed by an audio system including a processor and a plurality of loudspeakers, comprises receiving an audio signal to be output to a listener, obtaining a first Head Related Transfer Function (HRTF) corresponding to a first predefined listening pose of the listener, obtaining a second HRTF corresponding to a second predefined listening pose of the listener, determining, for each of the plurality of loudspeakers a respective loudspeaker signal using the audio signal, the first HRTF, and the second HRTF, and simultaneously outputting, via the plurality of loudspeakers using the loudspeaker signals, a first sound signal for the first predefined listening pose corresponding to the first HRTF and limited to a first predefined spatial zone, and a second sound signal for the second predefined listening pose corresponding to the second HRTF and limited to a second predefined spatial zone different from the first predefined spatial zone.

Spatial sound improvement for seat audio using spatial sound zones

A system and method for generating a virtual soundstage in a listening environment having a compact speaker array centrally positioned in a listening environment. A listener is sitting offset from the speaker array and the virtual soundstage is generated in front of a listener. A signal processing unit is configured to receive an incoming audio signal, to process left and right channel signals of the incoming audio signal to generate a null, and to steer the null toward one ear of a listener thereby generating a virtual sound source that is offset from the center of the listening environment. Virtual sound sources are generated in front of, to the left of, and to the right of the listener.
