## 語法

```cpp theme={null}
HRESULT SetShapeXmaSampleRate(  
         SHAPE_XMA_CONTEXT* context,  
         UINT32 sampleRate  
)  
```

<a id="parametersSection" />

### 參數

*context*   \_Inout\_\
類型: [SHAPE\_XMA\_CONTEXT](/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context)\*

[SHAPE\_XMA\_CONTEXT](/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context) 物件的指標。

*sampleRate*   \
類型: UINT32

取樣率 (以赫茲為單位)。

<a id="retvalSection" />

### 傳回值

類型: HRESULT

HRESULT 成功或錯誤碼。

<a id="remarksSection" />

## 備註

*sampleRate* 參數會轉換為 [SHAPE\_XMA\_SAMPLE\_RATE](/zh-TW/reference/audio/shapexmacontext/enums/shape_xma_sample_rate) 列舉的成員，如下表所示。

| 值 | 成員 |
| - | - |
| \<= 24000 | SHAPE\_XMA\_SAMPLE\_RATE\_24K |
| 24001-32000 | SHAPE\_XMA\_SAMPLE\_RATE\_32K |
| 32001-44100 | SHAPE\_XMA\_SAMPLE\_RATE\_44\_1K |
| >= 44101 | SHAPE\_XMA\_SAMPLE\_RATE\_48K |

若要使用 [SHAPE\_XMA\_SAMPLE\_RATE](/zh-TW/reference/audio/shapexmacontext/enums/shape_xma_sample_rate) 列舉的成員而非整數來設定取樣率，請使用 [SetShapeXmaSampleRate(SHAPE\_XMA\_CONTEXT\*, SHAPE\_XMA\_SAMPLE\_RATE)](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmasamplerate)。

若要取得目前的取樣率，請使用 [GetShapeXmaSampleRate](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmasamplerate)。

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