Pitch analysis and silence vs. speech detection with SignalLab

[Dave]

To determine how often something is called it's easy to use a counter (global int) increased in the event and have it read and cleared once a second by a timer for example.

If you connect the GenericReal to the FFT-SpectrumOutputPin the inputbuffer simply represents the spectrumdata (volume per frequency in real/double) and you can get the buffersize by calling InBuffer.GetSize().
