Abstract

A signal processing apparatus generates a window signal, transforms the window signal into a frequency spectrum, and adjusts an amplitude component of the frequency spectrum. Then, the signal processing apparatus applies inverse transform to the amplitude component after adjustment and to a phase component of the frequency spectrum to generate a frame signal, and identifies an overlap segment such that the absolute value of the amplitude of the frame signal at at least one end of the overlap segment becomes smaller than the absolute value of the amplitude of the frame signal at a corresponding end of an overlapping section. Then, in the identified segment, the signal processing apparatus adds and compounds the frame signal corresponding to an immediately preceding frame and the frame signal corresponding to a processing-target frame.
