)  
```

### 参数

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

指向 [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/structs/shape_xma_context.md) 对象的指针。

### 返回值

Type: void\*

## 备注

重叠相加缓冲区的大小为单声道 256 字节或立体声 512 字节。

若要通过指针设置重叠相加缓冲区的地址,请使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer.md)。

若要通过物理地址设置重叠相加缓冲区的地址,请使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2.md)。
