# GetShapeFiltVolOutputGainTarget

取得輸出增益目標值。

## 語法

```cpp theme={null}
float GetShapeFiltVolOutputGainTarget(  
         const SHAPE_FILTVOL_CONTEXT* context  
)  
```

### 參數

*context*   \_In\_\
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。

### 傳回值

類型: float

增益目標值。

## 備註

增益目標值和增益是範圍介於 -2.0 到 2.0 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 |

若要變更輸出增益目標值,請使用 [SetShapeFiltVolOutputGainTarget](/zh-TW/reference/audio/shapefiltvolcontext/functions/setshapefiltvoloutputgaintarget)。
