FFT8

Fast Fourier Transform with eight samples.

Syntax

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

Parameters

pReal   _Inout_updates_(uCount * 2)
Type: XMVECTOR* __restrict Real components of the FFT. Must have at least uCount × 2 elements. pImaginary   _Inout_updates_(uCount * 2)
Type: XMVECTOR* __restrict Imaginary components of the FFT. Must have at least uCount × 2 elements. uCount   _In_
Type: size_t Number of FFT iterations.

Return value

Type: void None.

Remarks

For FFTs with a number of samples that are less than or equal to 16, use FFT16, FFT8, or FFT4. All buffer parameters must be 16-byte aligned. Audio data must be FLOAT32 mono.
