Shouldn't the spectrum of null-test delta look something like that (well, mine does)?..

I think it depends on what is captured in the recording and the software. The program I used above is a picture of the whole jazz tune in time (at the bottom it shows the elapsed  time).

Post the spectrum of your null-test delta signal for comparison.

I did post the spectrum analyzer from Izotope RX. That is how it looks in that program. It is the last pic in my original post.

What you posted is a spectrogram, not spectrum...

Oops, forgot to reset my Audacity setting of 16-bit sample precision to 32-bit float...
