• eComplexDataHandling defines the action that is performed using Call(), e.g. extracting real or imaginary parts, calculating the amount or phase of the complex input data.
• nInLength is the length of the input array.
• fPhaseThreshold defines the limit value for rolling out the phase. The value Pi is used as a rule.
• nChannels defines the number of independent channels. This must be greater than zero.
