Functions
void	r8b::calcMinPhaseTransform (double *const Kernel, const int KernelLen, const int LenMult=2, const bool DoFinalMul=true, double *const DCGroupDelay=R8B_NULL)
	Calculates the minimum-phase transform of the filter kernel, using a discrete Hilbert transform in cepstrum domain.

Detailed Description

Real-valued FFT transform class.

This file includes FFT object implementation. All created FFT objects are kept in a global list after use, for a future reusal. Such approach minimizes time necessary to initialize the FFT object of the required length.
