Patent ID: 8848952

Claim:
An audio reproduction apparatus which performs signal processing on an audio signal so that, when the audio signal is reproduced by a first speaker and a second speaker which actually exist, a viewer perceives the audio signal as being reproduced by a virtual speaker, the virtual speaker being assumed to be placed between the first speaker and the second speaker with respect to a predetermined viewing position, said audio reproduction apparatus comprising: a first signal processing unit configured to equalize a first audio signal using a first equalizer characteristic that converts a characteristic of an audio signal perceived as being reproduced at a position of the first speaker with respect to the viewing position to be perceived as being reproduced at a position of the virtual speaker with respect to the viewing position; a second signal processing unit configured to equalize the first audio signal using a second equalizer characteristic that converts a characteristic of an audio signal perceived as being reproduced at a position of the second speaker with respect to the viewing position to be perceived as being reproduced at the position of the virtual speaker with respect to the viewing position; a first level adjuster which performs level adjustment, using a first coefficient, on an output signal of said first signal processing unit; a second level adjuster which performs level adjustment, using a second coefficient, on an output signal of said second signal processing unit; a first adder which adds, and outputs to the first speaker, an output signal of said first level adjuster and the first audio signal; and a second adder which adds, and outputs to the second speaker, an output signal of said second level adjuster and a second audio signal to be reproduced by the second speaker.
