LPSVD Macro??

I have been looking for snippets or full Macro code dealing with LPSVD - Linear Prediction Single Value Decomposition, but have not been successful as of yet. In short, it is a much more efficient and accurate method of extracting frequency information out of a time domain data set as compared to the typically used FFT (fast Fourier transform) method when you may or may not have truncated damping exponentials.

I know spectroscopists have been using this method since ~1985, and I don't want to "reinvent the wheel" by spending days/weeks writing my own Macro for it.

Any help, suggestions or direction would be greatly appreciated!

Thanks!
