# GetShapeXmaOverlapAddBuffer

Gets the address of the overlap-add buffer.

<a id="syntaxSection" />

## Syntax

```cpp theme={null}
void* GetShapeXmaOverlapAddBuffer(  
         const SHAPE_XMA_CONTEXT* context  
)  
```

<a id="parametersSection" />

### Parameters

*context*   \_In\_\
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.

<a id="retvalSection" />

### Return value

Type: void\*

Pointer to the overlap-add buffer.

<a id="remarksSection" />

## Remarks

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

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

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).
