Abstract
An acoustic processing device unit is provided with: an input reception unit configured to receive an input of a value of a parameter defining a phase difference to be provided between a pair of audio signals; a filter coefficient calculation unit configured to calculate a filter coefficient group corresponding to each of the pair of audio signals based on the input value received by the input reception unit; and a filter processing unit configured to provide a phase difference defined by the input value between the pair of audio signals by performing filter processing on each of the pair of audio signals based on the filter coefficient group calculated by the filter coefficient calculation unit. The parameter above includes a center frequency of the phase difference provided between the pair of audio signals, a quality factor, and a phase difference at the center frequency.
