Try to extract and run the FFT (Fast Fourier Transform) and FWT (Fast Wavelet Transform) classes from Squeak 4.5 image as a first draft.

i translated squeaks fft. the fwt, yes, is just a fast wavelet transform and as a general wavelet package leaves something to be desired imo. hence i didnt touch it at the moment. werner

There is a Math-FastFourierTransform package.
