Converts complex components to polar form.

void FFTPolar(XMVECTOR* pOutput,
    const XMVECTOR* pInputReal, const XMVECTOR* pInputImaginary,
    const size_t uLength);

Parameters

pOutput

[out] Caller supplied output buffer to receive samples in polar form. pOutput must have at least uLength ÷ 4 elements.

[in] Input buffer containing the real components of a Fast Fourier Transform. pInputReal must have at least uLength ÷ 4 elements.

[in] Input buffer containing the imaginary components of an FFT. pInputImaginary must have at least uLength ÷ 4 elements.

[in] FFT length in samples. uLength must be a power of 2 greater than or equal to 4.

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