Help! Need to find a method for de-spreading harmonics

Hello! I was handed a restoration job where the audio was affected in the weirdest way... it's almost like ring modulated and the harmonic content of the singer has been warped in such a way that the lows are too low and the highs are too high. Almost like the pitch has been spread so the harmonic range which was once from 200Hz - 8k now goes down to 20Hz and up to 18k. Again, it's really weird and I have no idea what happened. But I'm curious if there are any plugins or programs which offer a solution for this. I want to basically scale the pitch, de-spread it, squeeze it, whatever. The only thing I've seen which is close to this is the Track Oscillator in Logic. But this doesn't exactly do what i need. I really need an FFT tool which can chop up the frequency domain and move each closer to a fundamental frequency. Any ideas?
