摘要：
A speaker array apparatus for outputting sound beams of a plurality of channels based on audio signals of the plurality of channels, includes a directivity control section that controls a directivity of at least one of the sound beams of the channels so as to generate one or more pairs of the sound beams of the channels having roughly the same directivity, and a frequency characteristic applying section that applies a frequency characteristic to the audio signal corresponding to one of the sound beams of the channels in the one or more pairs to change a sound image localization position of the one of the sound beams of the channels in the one or more pairs.
