ABSTRACT:
FFT section102transforms a windowed input noise signal into a frequency spectrum. Spectral model storing section103stores model information on spectral models. Spectral model series calculating section104calculates spectral model number series corresponding to amplitude spectral series of the input noise signal, using the model information stored in spectral model storing section103. Duration model/transition probability calculating section105outputs model parameters using the spectral model number series calculated in spectral model series calculating section104. It is thereby possible to synthesize a background noise with perceptual high quality.
