Abstract:
An audio reproduction apparatus includes: a signal processing unit that converts an audio signal into N channel signals, where N is an integer greater than or equal to 3; and a speaker array including N speaker elements that respectively output the N channel signals as reproduced sound, wherein the signal processing unit includes: a beam formation unit that performs a beam formation process of resonating the reproduced sound output from the speaker array at a position of one ear of the listener; and a cancellation unit that performs a cancellation process of preventing the reproduced sound output from the speaker array from reaching a position of the other ear of the listener.
