摘要: A processing apparatus estimates a noise amplitude spectrum of included in sound signal. The includes an calculation part configured to calculate the signal for each one frames obtained from dividing into units time; and estimation estimate detected frame. first based on difference between calculated by frame occurring before is detected, second attenuation function spectra after detected.
