Classes
struct	PffftSetupDeleter
struct	PffftAllocatorBase
struct	PffftAllocator< T >
	Aligned memory is required by pffft, so this defines an allocator. More...
struct	PffftAllocator< T >::rebind< U >
struct	PffftAlignedCount
struct	PffftFloats
	A pointer to an aligned range of floats. More...
struct	PffftConstFloats
	A read-only pointer to an aligned range of floats. More...
struct	PffftFloatVector
	A vector of floats guaranteeing alignment as demanded by pffft. More...
class	PowerSpectrumGetter
	Much faster that FFT.h's PowerSpectrum, at least in Short-Time Fourier Transform-like situations, where many power spectra of the same size are needed. Currently only power spectrum, but may be generalized to other uses. More...
