C# Class Accord.Audio.ComplexSignal

Complex audio signal.

A complex discrete-time signal is any complex-valued function of integers. This class is used to keep audio signals represented in complex numbers so they are suitable to be converted to and from the frequency domain in either analytic or Fourier transformed forms.
