Abstract:
A sound field device is disclosed that comprises an elevation cue estimator, a low-frequency filter estimator, and a high-frequency filter estimator. The elevation cue-estimator is configured to estimate an elevation cue of a head-related transfer function (HRTF) of at least one listener. The low-frequency filter estimator is configured to estimate one or more low-frequency filter elements based on the elevation cue. The high-frequency filter estimator is configured to estimate one or more high-frequency filter elements based on the elevation cue. An estimation method of the low-frequency filter estimator is different from an estimation method of the high-frequency filter estimator. The one or more low-frequency filter elements and the one or more high-frequency filter elements are for driving an array of loudspeakers to generate an elevated sound impression at a bright zone.

Claim (Index 13):
The audio system of  claim 12 , wherein the high-frequency filter estimator comprises:\n a loudspeaker selection unit configured to select one or more active loudspeakers such that locations of the one or more active loudspeakers overlap with a projection of the bright zone on the array of loudspeakers; and a loudspeaker weight assigning unit configured to assign one or more frequency-dependent weights to the one or more active loudspeakers.
