Abstract
An acoustic signal output control section extracts, from an acoustic signal, a low-frequency-component acoustic signal and a high-frequency-component acoustic signal. A sound image localization processing filter section performs a sound image localization process on the low-frequency-component acoustic signal. The low-frequency-component acoustic signal having been subjected to the sound image localization process is outputted from loudspeakers in an AV rack loudspeaker apparatus. A television sound image localization processing filter section performs a sound image localization process on the high-frequency-component acoustic signal. The high-frequency-component acoustic signal having been subjected to the sound image localization process is outputted from loudspeakers in a television via HDMI communication sections.
