)  
```

<a id="parametersSection" />

## 備註

此函式會設定內容中實際的聲道數目。(在 [SHAPE\_XMA\_CONTEXT](/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context) 物件中，`numChannels` 成員包含的值為 0 \[單聲道] 或 1 \[立體聲]。)

若要取得目前的聲道數目，請使用 [GetShapeXmaNumChannels](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmanumchannels)。
