It won't because the vibrato frequency is too low, around 10hz.

Or just be fast to react, else this vibrato amplitude would be 
smoothed out.

In non-realtime, everything is possible, you can have a bigger

For example, some use dynamic programming for pitch detection.

Whatever the method, it's important to spend a lot of time in 
tuning.
