Detailed Description

Complex Fast Fourier Transform.

Outputs a window, or block of samples based on the FFT window. Complex FFT returns the real and imaginary parts via a struct.

Constructor & Destructor Documentation

pd::complexFFT::complexFFT ( )

If you would like to change the window size, default is 64, use ::setFFTWindow() which is inherited from PdMaster.

pd::complexFFT::complexFFT ( int ws )

Copy constructor. You can manually set the window size here.

Member Function Documentation

double * pd::complexFFT::perform	(	double	real,
		double	imaginary
	)

This function returns a block of complex samples, which are the real and imaginary parts.

complexFFT returns a block of samples that are processed by mayer_fft(). For complex FFT it returns the real and imaginary parts. The Mayer FFT methods pass all values by reference. You can do whatever with these samples. To resynthesize use cIFFT and divide by window size.
