Core Real FFT process
- Parameters:
-
[in] *pSrc points to the input buffer. [in] fftLen length of FFT. [in] *pATable points to the twiddle Coef A buffer. [in] *pBTable points to the twiddle Coef B buffer. [out] *pDst points to the output buffer. [in] modifier twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table.
- Returns:
- none.
