<a id="syntaxSection" />

## Syntax

```cpp theme={null}
HRESULT SetShapeXmaOverlapAddBuffer(  
         SHAPE_XMA_CONTEXT* context,  
         void* buffer  
)  
```

<a id="parametersSection" />

### Parameters

*context*   \_Inout\_\
Type: [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context)\*

Pointer to a [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context) object.

*buffer*   \_In\_\
Type: void\*

Pointer to the overlap-add buffer. Must be 128-byte aligned.

<a id="retvalSection" />

### Return value

Type: HRESULT

HRESULT success or error code.

<a id="remarksSection" />

## Remarks

The size of the overlap-add buffer must be 256 bytes for mono or 512 bytes for stereo.

To set the address of the overlap-add buffer by using a physical address, use [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2).

To get the current size of the overlap-add buffer, use [GetShapeXmaOverlapAddBuffer](/reference/audio/shapexmacontext/functions/getshapexmaoverlapaddbuffer).

For more information, see the [XMA](/build/console-features/audio/overviews/shape-overview#ID4EYD) section of [Overview of SHAPE](/build/console-features/audio/overviews/shape-overview).
