Abstract:
A signal processing apparatus includes a transform unit configured to orthogonally transform an audio signal; an analysis unit configured to analyze the audio signal orthogonally transformed by the transform unit and estimate a very high frequency stationary signal component; and a signal processing unit configured to perform signal processing to reduce the very high frequency stationary signal component estimated by the analysis of the analysis unit with respect to the audio signal.
