摘要：A phase control signal generation device generating a phase control signal foreach of frequency bands for an audio signal converted into a frequency domain, thephase control signal generation device comprising: a setting change means that is able tochange setting of a propagation delay time for each of predetermined frequency bands;a difference obtaining means that obtains a difference between propagation delay timesbefore and after setting change; an updating means that updates a phase control

amount of the frequency band for which the propagation delay time is changed, based onthe obtained difference; and a phase control signal generating means that generates aphase control signal of each frequency band by performing a smoothing process for thephase control amount in a frequency domain using the updated phase control amount.
