FYI I cross-posted my request on a Swedish forum and i got this link for
ffttools by mdsp at smartelectronix.com

http://mdsp.smartelectronix.com/product/ffttools/

the warp tool is advertising the exact function i dreamed of... sad
thing is that it is for windOSx only ;'(

Anyone has got any experience with that plugin?

I also got a link to Audacity's spectrum analyzer.

But it is unclear whether or not you can export the picture and if so,
in what scale the colors should be inversed....
