A speaker array apparatus capable of carrying out directivity control over a wide frequency range with reduced processing load. In the speaker array apparatus, an audio signal input from a signal input unit is divided into components by a signal divider unit to generate divided audio signals of different frequency ranges. The divided audio signals are amplified by amplifier units of a signal processing unit with gains set in accordance with window functions set to the amplifier units, and a sound emission unit emits sounds based on the amplified audio signals, whereby desired directional characteristics can be attained over a wide frequency range and an amount of calculation in the processing by the signal processing unit can be reduced.
