57 Abstract AB [EN] Disclosed is a device for processing an input signal comprising a number of sub-signals which are allocated to discrete transmitting and receiving units that are disposed in predetermined geometrical positions relative to a space. The inventive device encompasses an apparatus (101) for supplying a plurality of wavefield components, the superposition of which results in a combined wavefield that is expandable in said space, the plurality of wavefield components being derived from the input signal by dividing the wavefield based on orthogonal basic wavefield functions and the predetermined geometrical positions. The inventive device further encompasses a plurality (107) of individual filters, one of the plurality of wavefield components being associated with an individual filter. The individual filter is configured to influence the associated wavefield components such that a plurality of filtered wavefield components representing a processed input signal are obtained relative to the plurality of individual filters (107) at the output end.
