ABSTRACT:
A spectral distance calculator includes a calculator for performing spectral distance calculations to compare a spectrum of an an input signal in the presence of a noise signal and a reference spectrum. A memory pre-stores a noise spectrum from the noise signal. A masking unit masks the spectral distance between the input spectrum and the reference spectrum with respect to the pre-stored noise spectrum.
