Pitch-correction for off=center vinyl?

I have nothing at all to add to this thread really but just wanted to say I really like the words

värttinä and sukkularihmasto

Finnish looks like its a cool language.

 

^ spindle [1: MOT English-Finnish 4.1]

spindle ['spɪndl] s 1 värttinä, kehrä ■ s 2 tekn kara, kehrä, teli ■ s 3 biol sukkularihmasto

I think it's correct! I meaned the small nut or knob on the turntable, where you insert the LP in a manner slighly resebling the this album cover:

The problem is that as the radius increases, the interval increases. so with each second of playback the interval needs to be adjusted. IMO it's not possible to keep the changes in sync with the deviations.

Wow! (sorry, bad joke but I couldn't resist)
 
None of the pitch correction software I know of would work...the quality of the results would be as inconsistent as the pitch of the original. They're mostly useless unless it's a monophonic signal.

Even a modulated pitch shift wouldn't work too well- even if you managed to lock it to the right time and pitch deviation for one revolution, it would be slightly off on the next. I suppose a real genius could devise an algorithm to compensate, if they knew the exact deviations of pitch over time.

You'd probably have more luck trying to re-drill and then reinforce the center hole so that the spindle doesn't slip into the old hole. I know I wouldn't dare it on a rare record, though...
