Abstract:
The disclosure relates to an audio signal processing apparatus for processing an input audio signal, comprising a filter unit comprising a plurality of filters, each filter configured to filter the input audio signal to obtain a plurality of filtered audio signals, each filter designed according to an extended mode matching beamforming applied to a surface of a half revolution, the surface partially characterizing a loudspeaker enclosure shape, a plurality of scaling units, each scaling unit configured to scale the plurality of filtered audio signals using a plurality of gain coefficients to obtain a plurality of scaled filtered audio signals, and a plurality of adders, each adder configured to combine the plurality of scaled filtered audio signals, thereby providing an output audio signal for producing a sound field having a beam directivity pattern defined by the plurality of gain coefficients.

Claim (Index 13):
A sound emission apparatus ( 120 ) comprising:\n a loudspeaker enclosure ( 121 ) comprising a sound emission section ( 121 a ) and a rear section ( 121 b ), wherein the sound emission section ( 121 a ) is coupled to or integral with the rear section ( 121 b ) and the sound emission section ( 121 a ) generally defines a surface of a half revolution about an axis extending along a length of the loudspeaker enclosure ( 121 ); and at least one transducer array ( 123 a,b ) mounted on the sound emission section ( 121 a ) of the loudspeaker enclosure ( 121 ), wherein a plane passing through the transducer array ( 123 a,b ) is orthogonal to the axis, the at least one transducer array ( 123 a,b ) being curved such that the at least one transducer array ( 123 a,b ) conforms to the curvature of the surface of the half revolution or at least one transducer array mounted within the loudspeaker enclosure ( 121 ) and connected to an array of waveguides defining an array of sound emission ports in the sound emission section ( 121 a ) of the loudspeaker enclosure ( 121 ), wherein a plane passing through the array of sound emission ports is orthogonal to the axis, the array of sound emission ports being curved such that the array of sound emission ports conforms to the curvature of the surface of the half revolution.
