I think many functions from the Octave signal toolbox, and octave-forge
toolbox are useful for this purpose. I'm not familiar with the details 
of the
spectrum analysis, apodization etc to help you here. A free software package
called fityk (unrelated to Octave) works for curve-fitting as applied to
spectrum analysis. Maybe you can look at that.
