WDL_fft_8()

void WDL_fft_8(double *buf, int len, int isInverse)

WDL_fft_8 performs a forward or inverse complex FFT. len must be 16,32,64,128,256,512,1024,2048,4096,8192,16384 or 32768. the buf must point to len*2 doubles. if isInverse is set then it is an inverse transform. no scaling is done so an FFT followed by an iFFT will result in the values being scaled up by len. the output is permuted, so a function to quickly access the permuted elements is provided (WDL_fft_permute).

Parameters

double *buf,
int len,
int isInverse

Returns

void
