Detailed Description

Forward FFT unit generator is an Effect because it handles an input It puts spectral frames in the output buffer and then broadcasts a change message, so clients are expected to observe it.

Public Member Functions
	FFT (UnitGenerator &in, CSLFFTType type=CSL_FFT_REAL, FFTFlags flags=kFFTMeasure, int size=CGestalt::blockSize())
	Default size to the buffer size and flags to measure.
	~FFT ()
int	fftSize ()
	no setter -- create a new FFT to change size
void	nextBuffer (Buffer &outputBuffer) throw (CException)
Public Attributes
CSL_FFTW_cmplx *	mCmplxSpectrum
	Buffer to store the spectrum.
CSL_FFTW_sample *	mRealSpectrum
	Temp buffer for spectrum.
bool	mOverwriteOutput
	whether to replace the output with the input (or the spectrum) after signalling observers
Protected Member Functions
void	initialize (FFTFlags flags)
Protected Attributes
int	mFFTSize
	This should be unsigned, but is signed for compatability with FFTW.
CSLFFTType	mType
	real or complex results
CSL_FFTW_plan	mPlan
	Plan for IFFT.
CSL_FFTW_sample *	mSampleBuffer
	Buffer to store samples.
CSL_FFTW_sample *	mInputBuffer
	Buffer to store past input.
CSL_FFTW_sample *	mWindowBuffer
	Buffer to store window.
