cTransformFFT

Description

This component performs an FFT on a sequence of real values (one frame), the output is the complex domain result of the transform. Use the cFFTmagphase component to compute magnitudes and phases from the complex output.

Type hierarchy

cDataProcessor → cVectorProcessor → cTransformFFT

Fields

• inverse (numeric) [default: 0.0]

  1 = perform inverse real FFT

• zeroPadSymmetric (numeric) [default: 1.0]

  1 = zero pad symmetric (when zero padding to next power of 2), i.e. center frame and pad left and right with zeros. New since version 2.3: this is the default, but should not affect FFT magnitudes at all, only phase.
