Is there any application that can convert songs with a really low
sample rate (8 khz) to 44.1 by extrapolating/cloning lower bands into
the missing higher frequency shelf?
Can't work. (More properly, I should say that it can't yield any better
result than the original 8kHz recording.)
Think digital pictures. Think of a little thumbnail, say 150 x 250
pixels that you resize to 1500 x 2500 pixels. It'll be bigger, but won't
look any better than the little original. Basically the same thing you'd
be doing with the audio file.

I'm aware it's not possible to restore something out of nothing.
That's not what I asked for. I asked if any program exists that tries
to replicate the missing higher frequencies by extrapolating from the
audio that already exists. Pseudo-high quality, pseudorestoration,
call it what the **** you want.
Example:
http://i26.tinypic.com/35atabp.jpg Song at 12 khz
http://i32.tinypic.com/intlw6.jpg Song at 22 khz (upper frequencies
restored)
Notice how the pattern is predictable. Any program that does even a
half-ass job of this is desirable. Anyone got any leads what to look
for?
