# SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)

設定重疊相加 (overlap-add) 緩衝區的位址。

## 語法

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

### 參數

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

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

*buffer*   \_In\_\
類型: void\*

重疊相加緩衝區的指標。必須以 128 位元組對齊。

### 傳回值

類型: HRESULT

HRESULT 成功或錯誤碼。

## 備註

重疊相加緩衝區的大小必須為 256 位元組 (單聲道) 或 512 位元組 (立體聲)。

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)。

若要取得目前重疊相加緩衝區的大小，請使用 [GetShapeXmaOverlapAddBuffer](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/functions/getshapexmaoverlapaddbuffer.md)。
