C# Class Accord.Audio.ComplexFilters.EnvelopeFilter

Hilbert transform based envelope detector.

This method works by creating the analytic signal of the input by using a Hilbert transform. An analytic signal is a complex signal, where the real part is the original signal and the imaginary part is the Hilbert transform of the original signal.

The complex envelope of a signal can be found by taking the absolute (magnitude) value of the analytic signal.
