Yes, so that will generate sidebands in the frequency spectrum,
like FM synthesis, right?
It won't because the vibrato frequency is too low, around 10hz.
So in order to pick up fast vibrato I would assume you would
also need to do analysis of the spectrum, or?
Or just be fast to react, else this vibrato amplitude would be
smoothed out.
So it is a problem for real time, but in non-real time you can
work your way backwards and fill in the missing parts before
doing resynthesis? I guess?
In non-realtime, everything is possible, you can have a bigger
analysis window and much less problems.
For example, some use dynamic programming for pitch detection.
I've read the Laroche and Dowson paper in detail, and more or
less know it by heart now, but maybe you are thinking about
some other paper? Their paper was good on the science part, but
they leave the artistic engineering part open to the reader...
;-) More insight on the artistic engineering part is most
welcome!!
Whatever the method, it's important to spend a lot of time in
tuning.
