quote from manuual of IPP:

IppStatus ippiFFTFwd_RToPack_ (const Ipp8u*

pSrc, int srcStep,

Ipp32s*

pDst, int dstStep, const IppiFFTSpec_R_32s* pFFTSpec,

int

scaleFactor, Ipp8u* pBuffer);

Supported values for

mod:

8u32s_C1RSfs

8u32s_C3RSfs

8u32s_C4RSfs

8u32s_AC4RSfs

There nowhere any explanation what are the modes are!

Is there any more valuable documentation about this?
