SIGNAL ANALYZING APPARATUS, METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a signal analyzing apparatus that can remove linear noise parallel to frequency axis.SOLUTION: A signal analyzing apparatus includes a setting unit and a generation unit. The setting unit sets components obtained by smoothing the acquired spectrogram as a reference level. The generation unit generates a spectrogram so that the level of the input spectrogram becomes lower when the level of the spectrogram is low relative to the reference level.
