# GetShapeXmaOverlapAddBuffer

取得重疊相加 (overlap-add) 緩衝區的位址。

## 語法

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

### 參數

*context*   \_In\_\
類型：[SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context.md)\*

指向 [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context.md) 物件的指標。

### 傳回值

類型：void\*

指向重疊相加緩衝區的指標。

## 備註

重疊相加緩衝區的大小，單聲道為 256 位元組，立體聲為 512 位元組。

若要使用指標設定重疊相加緩衝區的位址，請使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer.md)。

若要使用實體位址設定重疊相加緩衝區的位址，請使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2.md)。

如需詳細資訊，請參閱 [SHAPE 概觀](https://docs.xbox.com/zh-TW/build/console-features/audio/overviews/shape-overview.md)中的 [XMA](https://docs.xbox.com/zh-TW/build/console-features/audio/overviews/shape-overview.md#ID4EYD) 一節。
