Abstract: Disclosed is a method for directionally reproducing an input audio signal by a transducer array comprising a plurality of transducers, the method comprising receiving said input audio signal and processing by signal processing to generate a processed audio signal, the processing comprising filtering harmonics in a directionally controllable frequency band, each of said harmonics corresponding to a lower order harmonic in a bass frequency band, wherein said bass frequency band comprises frequencies below said directionally controllable frequency band, generating a plurality of driving signals for said plurality of transducers, wherein said plurality of driving signals are generated on the basis of said processed audio signal by application of directional control filters, and reproducing directional sound representing said input audio signal based on said plurality of generated driver signals using said transducer array.

Abstract: The invention relates to a method for processing an input audio signal to be perceived in an acoustical environment comprising at least a first sound zone and a second sound zone, comprising the steps of receiving an input audio signal, processing said input audio signal using signal processing to generate a processed audio signal, determining an expected loudness in a second sound zone of said acoustical environment, of acoustically reproducing said processed audio signal by a loudspeaker system for a first sound zone of said acoustical environment, wherein said determining an expected loudness is at least with respect to a bass frequency band; and automatically adjusting, on the basis of said determined expected loudness in said second sound zone, one or more level-dependent filters of said processing. The invention further relates to a loudspeaker system for processing an input audio signal to be perceived in an acoustical environment.
