Abstract
An acoustic processing device performs acoustic processing in a space having a first listening position and a second listening position apart from the first listening position. The acoustic processing device includes a first input unit, a first output unit, and a signal processing circuit. The first input unit receives a first sound source signal to be reproduced at the first listening position. The first sound source signal includes a first left-channel signal and a first right-channel signal. The first output unit outputs the first sound source signal to a first speaker group including a first speaker disposed near a place of a head of a listener at the first listening position. The signal processing circuit draws out a first common signal common to both the first left-channel signal and the first right-channel signal and outputs the first common signal to the first speaker.
