Detailed Description

Fast Fourier Transform. Frequency analysis. for 8 bit values. iLengthBits = Window Size = power of 2.

Constructor & Destructor Documentation

cFFT()

GrayLib::cFFT::cFFT	(	BIT_ENUM_t	iLengthBits,
		bool	bAutoScale = true
	)

Todo:

Fix this to be calculated on demand for any window size. based on cValueCurve?
