# GetShapeEqCompGain

获取压缩器的输出（补偿）增益。

## 语法

```cpp theme={null}
float GetShapeEqCompGain(  
         const SHAPE_EQCOMP_CONTEXT* context  
)  
```

### 参数

*context*   \_In\_\
类型：[SHAPE\_EQCOMP\_CONTEXT\*](/reference/audio/shapeeqcompcontext/structs/shape_eqcomp_context)

指向 `SHAPE_EQCOMP_CONTEXT` 对象的指针。

### 返回值

类型：float

增益乘数。

## 备注

压缩器通过监视输入的电平并创建动态增益值来限制信号的动态范围。然后，压缩器将增益值作为信号的乘数，根据当前的输入信号电平对其进行相应的缩放。换句话说，压缩器是一种持续监视输入信号并进行自我调整的自动音量控制。

## 要求

**头文件：** shapeeqcompcontext.h
