Abstract:
1. A sound signal processing apparatus which generates a sound output signal input to a phase inversion type speaker, the apparatus comprising: a dividing unit which divides an input sound signal into a low frequency signal and a high frequency signal; a delaying unit which delays a phase of the high frequency signal; a correcting unit which changes a phase of the low frequency signal in accordance with a frequency of the input sound input signal; and a synthesizing unit which generates the sound output signal by synthesizing an output signal from said delaying unit and an output signal from said correcting unit, wherein said correcting unit corrects the phase of the low frequency signal to make the signal become in phase with the output signal from said delaying unit; and wherein the sound output signal generated by the synthesizing unit is used as the input to the phase inversion type speaker.
