I am not understanding how you use a spectrum analysis to correct pitch 
variations. Perhaps you can clarify a bit.

I think you mean "amplitude as a function of frequency" and not 
"amplitude vs. frequency"

I have programs that can display spectrum analysis. I am not aware of 
how it can reveal pitch variations.

So maybe I was not clear. I'm looking for a visual display of wow. Then 
I could use a pitch shifter, like the one in DCart, to make a fix for that.
