WebIFFT（逆快速傅里叶变换）则是FFT的逆运算，用于将频域信号转换回时域信号。如果您需要生成C语言代码，建议您使用某些库函数，例如FFTW（Fastest Fourier Transform in the West）库。如果您想自己编写代码，可以参考其他开源代码来实现FFT和IFFT。 WebFFT-based FIR Filter is a unit to perform the finite impulse responce filter based on the Fast Fourier Transform (FFT). It performs the convolution of the unlimited signal sequence with the synthesized impulse responce of the length of Ni=N/2 samples, where N = 64, 128, 256, 512, 1024. The data and coefficient widths are tunable in the range 8 ...

WebFFT3DFilter uses Fast Fourier Transform method for image processing in frequency domain. It is based on some advanced mathematical algorithms of optimal filtration. It works not locally, but makes some de-localized (block) processing. In 3D mode, it results in effect similar to partial motion compensation. http://www.avisynth.nl/index.php/FFT3DFilter
