## 备注

若要设置左输入缓冲区的地址,请使用 [SetShapeXmaInputBuffer0(SHAPE\_XMA\_CONTEXT\*, const void\*)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0.md) 或 [SetShapeXmaInputBuffer0(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0_2.md)。 若要设置右输入缓冲区的地址,请使用 [SetShapeXmaInputBuffer1(SHAPE\_XMA\_CONTEXT\*, const void\*)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1.md) 或 [SetShapeXmaInputBuffer1(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1_2.md)。

若要获取当前输入缓冲区,请使用 [GetShapeXmaCurrentInputBuffer](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/getshapexmacurrentinputbuffer.md)。
