Abstract
Provided is an acoustic signal processing device for producing an output sound meeting listener's preferences by adjusting attack sound, reverberation, and noise component. The device includes: an FFT section for transforming an input audio signal from a time-domain to a frequency-domain to calculate a frequency spectrum signal and for generating a first amplitude spectrum signal and a phase spectrum signal; an attack component controller () for controlling an attack component of the first amplitude spectrum signal to generate a second amplitude spectrum signal; a reverberation component controller () for controlling a reverberation component of the first amplitude spectrum signal to generate a third amplitude spectrum signal; a first adding section () for synthesizing the first amplitude spectrum signal, the second amplitude spectrum signal, and the third amplitude spectrum signal to generate a fourth amplitude spectrum signal; and an IFFT section for generating an audio signal transformed from a frequency domain to a time domain based on the fourth amplitude spectrum signal and the phase spectrum signal generated by the FFT section.
