Pitch analysis and silence vs. speech detection with SignalLab

I ended up using GenericReal but to get the pitch information you might want to connect it to the FFT-FrequencyOutputPin.
Then in the GenericReal callback I have used the argument "Arg" of type ProcessRealNotify and obtained the mean frequency of the last computed FFT window using Args.InBuffer.Mean().

Finally I have stored those values (the previous 60) in a queue and done my computations to check for the changes in the pitch level.

I hope this might be helpful for some other readers as well and I thank you Dave so much for your quick posting.
Great support!
