# Deinterleave

# Deinterleave

This function deinterleaves audio samples such that all samples corresponding to a specified channel are contiguous.

## Syntax

```cpp theme={null}
void DSP::Deinterleave(  
         XMVECTOR* __restrict pOutput,  
         const XMVECTOR* __restrict pInput,  
         const size_t uChannelCount,  
         const size_t uFrameCount  
)  
```

### Parameters

*pOutput*   \_Out\_writes\_((uChannelCount \* uFrameCount) / 4)\
Type: XMVECTOR\* \_\_restrict

Caller-provided array of XMVECTOR elements that receives the samples in deinterleaved form. It cannot overlap pInput, and it must have at least (*uChannelCount* × *uFrameCount*) ÷ 4 elements.

*pInput*   \_In\_reads\_((uChannelCount \* uFrameCount) / 4)\
Type: XMVECTOR\* \_\_restrict

Caller-provided array of XMVECTOR elements that supplies audio samples in interleaved form. It cannot overlap pOutput, and it must have at least (*uChannelCount* × *uFrameCount*) ÷ 4 elements.

*uChannelCount*   \_In\_\
Type: size\_t

Number of channels contained in the data. *uChannelCount* must be greater than 1.

*uFrameCount*   \_In\_\
Type: size\_t

Number of frames of valid data. *uFrameCount* must be greater than 0.

### Return value

Type: void

None.

## Remarks

As an example, audio of the form \[LRLRLR] becomes \[LLLRRR].
