Abstract: A method and an apparatus process an audio signal. The method of processing an audio signal includes: separating the audio signal into a first harmonic signal and a first percussion signal; adjusting gains of the first harmonic signal and the first percussion signal to generate a second harmonic signal and a second percussion signal; and adding the second harmonic signal and the second percussion signal. The method can generally improve the apparatus for controlling a gain and adopt a reproducing volume level to a current environment by separating the audio signal into a harmonic signal and a percussion signal to adjust a gain. The audio signal can have a high output level without non-linear distortion.
