Phase Correlation Meter

[resonant]

Yes there is a good GonioMeter.

But how can we create a Phase Correlation Meter similar to the one below?

@resonant you'll need to run your own algorithm. It's not too hard to make, go search google for something like phase meter algorithm or left-right correlation algorithm you should definitely find something. There are several ways for doing this depending on the complexity and the response needed.
