1. A signal processing method comprising:

  • a first step of performing predetermined processing to a frequency spectrum of a first frame signal of a predetermined length to which a predetermined window function is performed, to be converted into a time domain to generate a second frame signal; and

    a second step of adjusting a predetermined correcting signal having a same frame length as the second frame signal so that amplitudes of both ends of the correcting signal substantially become equal to amplitudes of both or one of frame ends of the second frame signal, and of correcting the second frame signal by subtracting the adjusted correcting signal from the second frame signal.
