I thought about it again (tonight before falling asleep :) and I think, from a
practical viewpoint, you are right: If you take a signal generated by a white
noise source and fed it into the STFT, you get a constant spectrum
(approximatly); so do you, if you take a delta-peak. And the diffrence is,
that the delta-peak contains all frequencies phase-aligned while white noise
contains all frequencies with random phase. I am sorry :(.
