Typedefs
typedef float	fftconvolver::Sample
	Type of one sample.
typedef Buffer< Sample >	fftconvolver::SampleBuffer
	Buffer for samples.

Functions
bool	fftconvolver::SSEEnabled ()
	Returns whether SSE optimization for the convolver is enabled.
template<typename T >
T	fftconvolver::NextPowerOf2 (const T &val)
	Returns the next power of 2 of a given number.
void	fftconvolver::Sum (Sample *FFTCONVOLVER_RESTRICT result, const Sample *FFTCONVOLVER_RESTRICT a, const Sample *FFTCONVOLVER_RESTRICT b, size_t len)
	Sums two given sample arrays.
template<typename T >
void	fftconvolver::CopyAndPad (Buffer< T > &dest, const T *src, size_t srcSize)
	Copies a source array into a destination buffer and pads the destination buffer with zeros.
void	fftconvolver::ComplexMultiplyAccumulate (SplitComplex &result, const SplitComplex &a, const SplitComplex &b)
	Adds the complex product of two split-complex buffers to a result buffer.
void	fftconvolver::ComplexMultiplyAccumulate (Sample *FFTCONVOLVER_RESTRICT re, Sample *FFTCONVOLVER_RESTRICT im, const Sample *FFTCONVOLVER_RESTRICT reA, const Sample *FFTCONVOLVER_RESTRICT imA, const Sample *FFTCONVOLVER_RESTRICT reB, const Sample *FFTCONVOLVER_RESTRICT imB, const size_t len)
	Adds the complex product of two split-complex arrays to a result array.
