# GetShapeFiltVolOutputGainTarget

获取输出增益目标值。

## 语法

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

### 参数

*context*   \_In\_\
类型:[SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context)\*

指向 [SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) 对象的指针。

### 返回值

类型:float

增益目标值。

## 注解

增益目标值和增益是范围在 -2.0 到 2.0 之间的幅度值,负值表示信号反相。

| 值           | 说明        |
| :---------- | :-------- |
| 1.0 到 2.0   | 放大        |
| 1.0         | 单位增益      |
| 0.0 到 1.0   | 增益衰减      |
| 0.0         | 静音        |
| -1.0 到 0.0  | 增益衰减;信号反相 |
| -1.0        | 单位增益;信号反相 |
| -2.0 到 -1.0 | 放大;信号反相   |

若要更改输出增益目标值,请使用 [SetShapeFiltVolOutputGainTarget](/reference/audio/shapefiltvolcontext/functions/setshapefiltvoloutputgaintarget)。
