# SetShapeFiltVolOutputGain

設定輸出增益。

## 語法

```cpp theme={null}
HRESULT SetShapeFiltVolOutputGain(  
         SHAPE_FILTVOL_CONTEXT* context,  
         float outputGain  
)  
```

### 參數

*context*   \_Inout\_\
類型：[SHAPE\_FILTVOL\_CONTEXT](/zh-TW/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context)\*

指向 [SHAPE\_FILTVOL\_CONTEXT](/zh-TW/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) 物件的指標。

*outputGain*   \
類型：float

輸出增益。

### 傳回值

類型：HRESULT

HRESULT 成功或錯誤碼。

## 備註

增益與增益目標是介於 -2.0 到 2.0 範圍內的振幅值，負值會反轉訊號。

| 值 | 描述 |
| :- | :- |
| 1.0 到 2.0 | 放大 |
| 1.0 | 單位增益 |
| 0.0 到 1.0 | 增益衰減 |
| 0.0 | 靜音 |
| -1.0 到 0.0 | 增益衰減；反轉訊號 |
| -1.0 | 單位增益；反轉訊號 |
| -2.0 到 -1.0 | 放大；反轉訊號 |

若要取得目前的輸出增益，請使用 [GetShapeFiltVolOutputGain](/zh-TW/reference/audio/shapefiltvolcontext/functions/getshapefiltvoloutputgain)。
