There's some useful research on automatic transcription by a Finn (who's
name, I'm afraid doesn't stick in my WASP memory).
The essence is that he isolates fundamentals through the prime harmonics
(that is if a set of frequencies are relatively prime then the root is
probably the fundamental).
You could use a phase vocoder and this approach to get very good results.
Probably complete overkill mind you!

This is a difficult problem (fundamental pitch tracking).
For voice signal, one recent algorithm which at least looks nice on
paper is developped by S. Basu in in PhD thesis about conversationnal
