Fast Fourier Transform with eight samples.

void FFT8 (XMVECTOR* pReal, XMVECTOR* pImaginary, const size_t uCount=1);

Parameters

pReal

[in, out] Real components of the FFT. Must have as least uCount × 2 elements.

pImaginary

[in, out] Imaginary components of the FFT. Must have at least uCount × 2 elements.

uCount

[in] Number of FFT iterations.

Remarks

All buffer parameters must be 16-byte aligned. Audio data must be 32-bit float mono.

This performs a split-radix FFT, radix 4 and 2.
