Abstract:
1. A signal processing method for a speaker array apparatus comprising: a signal divider; an amplitude adjuster having a plurality of gain amplifiers; a first speaker unit; and a second speaker unit, wherein the method comprises: a signal division step of dividing, with the signal divider, an input audio signal into a first audio signal of a first predetermined frequency range to generate a plurality of divided audio signals; a first output step of outputting, with the amplitude adjuster, a first divided audio signal of a first predetermined frequency range, among the plurality of divided audio signals, to the first speaker unit but not to the second speaker unit; a second output step of outputting, with the amplitude adjuster, a second divided audio signal of a second predetermined frequency range, among the plurality of divided audio signals, to the second speaker unit; and a third output step of outputting, with the amplitude adjuster, a third divided audio signal, among the plurality of divided audio signals, to the second speaker unit.
