Abstract
A frequency domain converter divides an input signal for each predetermined frame, and generates a first signal X(f, τ) for each first frequency division unit. A noise estimation signal generator generates a signal Y(f, τ) for each second frequency division unit wider than the first frequency division unit. A signal comparator calculates a representative value for each second frequency division unit based on the signal Y(f, τ) stored in a storage unit, and compares the representative value and the signal Y(f, τ) with each other for each second frequency division unit. A mask generator generates a mask M(f, τ), which determines a degree of suppression or emphasis for each first frequency division unit, based on a peak range of the signal X(f, τ), and a comparison result by the signal comparator. The mask application unit multiplies the signal X(f, τ) by the mask M(f, τ).
