Re: harmonic extraction

Dear Xueliang Zhang,

I agree with Yoshitaka.  You can certainly prime any complex component
of a complex tone.  The shorter the temporal gap between the two
tones, the better the decomposition of the more complex one.  Consider
the extreme case, where there is no temporal gap between the two
tones, and the more complex tone has just one more harmonic than the
less complex one.  What you will hear is a continuous drone of the
less complex tone, with a pure tone (the extra harmonic) switching on
and off periodically.
