Méthodes publiques

Méthode	Description
ComputeFrame ( short input, double output ) : void
ComputeTable ( int size ) : void	Call this with the size before using the FFT Fills in tables for speed
FFT ( double data ) : void	Compute the forward or inverse FFT of data, which is complex valued items, stored in alternating real and imaginary real numbers. The length must be a power of 2.
Initialize ( int frame_size, double window ) : void
RealFFT ( double data ) : void	Computes the real FFT.
