Over the years, the most useful FFT software I've had, is the (fairly

use in analysis and testing.


Hi Arny,

I am sure this is an useful tool, but without windowing the data, any
semblance to reasonable analysis is a house built on sand. I note in
your provided link to work you have done that you use Blackman
exclusively. This is at least a good first pass to achieving an
analysis, but any variety of work is going to be more demanding (the
Blackman window has its limitations), otherwise it is like looking
through glasses smeared with Vaseline.
