Provided is an audio signal processing device for adjusting attack sound, reverberation, and noise components, and matching the output sound to the listener preferences. The audio signal processing device comprises the following: an FTF unit for determining a frequency spectrum signal by converting an input audio signal from a time region to a frequency region, and generating a first amplitude spectrum signal and a phase spectrum signal; an attack component control unit (10) for generating a second amplitude spectrum signal by controlling the attack component of the first amplitude spectrum signal; a reverberation component control unit (20) for generating a third amplitude spectrum signal by controlling the reverberation component of the first amplitude spectrum signal; a first addition unit (40) for generating a fourth amplitude spectrum signal by synthesizing the first amplitude spectrum signal, the second amplitude spectrum signal, and the third amplitude spectrum signal; and an IFFT unit for generating, on the basis of the fourth amplitude spectrum signal and a phase spectrum signal generated by the FFT unit, an audio signal in which a frequency region was converted from a frequency region to a time region. |
