There's two categories in general. Realtime and file processing - you  
know, audio file in midi file out.

I've yet to run it through it's paces, but the commercial software I  
hear the most about is Melodyne.

though it's not cheap and MIDI output is more a fringe benefit rather  
than the focus of this pitch correction and harmony building  
software. Not realtime.

Something very legacy oriented but free is Opcode Studio Vision, an  
OS9 MIDI sequencer app that guitar-maker Gibson bought and gave up  
on, also not realtime.

In general you can say that the results get worse as the material  
gets more complex. Additionally the ability to deal with polyphonic  
input is, as far as I know still experimental. For instance if you  
have some simple flute music or one person singing "aaahhh" solo you  
would likely get something fairly clean and usable. The problem is  
most of what's interesting is far more complex and potentially is  
chock full of not quite right sounding material. From what I  
understand the problem lies in not only accuracy but what to ignore.  
The beginnings of sounds often contain unpitched material that can  
mistrack. On the other hand waiting until it's over leaves you with a  
lag and likelyhood that the rhythmic timing will wind up sloppy.
