Fixing/regenerating clipped audio?

[dansrfe]

I recently bought a bluray for an old movie and nearly all of the 6 channels have been run through a low-pass filter, center channel especially so. Now, I realize that clipped audio cannot be restored however is there a way to algorithmically generate the clipped high frequencies to a certain degree to mitigate the effects of the audio sounding "covered up"?

Thanks in advance.
