With a large enough table size, the phase vocoder can find the actual instantaneous frequencies of a signal (as averaged within the table size). Using a table size of 4096 or 8192 works fairly well for me. You can find a good phase vocoder in the book: Elements of Computer Music F. Richard "Dick" Moore Prentice-Hall
