Abstract
An audio signal processing deviceincludes a period detecting unitfor detecting the fundamental period of an input audio signal; a square wave generating unitfor generating, according to the fundamental period the period detecting unitdetects, a square wavewhose period is an integer multiple of the fundamental period; an amplitude correction coefficient generating unitfor calculating an amplitude correction coefficientapproximately equal and proportional to the intensity of the input audio signal; a first multiplierfor generating an amplitude-corrected square waveby multiplying the square waveby the amplitude correction coefficient; and an adderfor adding the amplitude-corrected square waveto the input audio signal
