Abstract
The present invention relates to a digital audio amplification device using harmonics and a method thereof, and more specifically, the invention differentially generates characteristics of harmonics (for instance, amplitude or frequency components of harmonics) of an audio signal in order to compensate the audio signal that exceeds a preset threshold value according to the amplitude and characteristics of the audio signal, if the audio signal exceeds the preset threshold value, thereby easily improving the amplitude and the pitch of audio during digital audio amplification.
