Abstract
FFT sectiontransforms a windowed input noise signal into a frequency spectrum. Spectral model storing sectionstores model information on spectral models. Spectral model series calculating sectioncalculates spectral model number series corresponding to amplitude spectral series of the input noise signal, using the model information stored in spectral model storing section. Duration model/transition probability calculating sectionoutputs model parameters using the spectral model number series calculated in spectral model series calculating section. It is thereby possible to synthesize a background noise with perceptual high quality.
