# SHAPE_EQCOMP_SIDECHAIN_MODE

> SHAPE_EQCOMP_SIDECHAIN_MODE

# SHAPE\_EQCOMP\_SIDECHAIN\_MODE

侧链模式。

## 语法

```cpp theme={null}
enum SHAPE_EQCOMP_SIDECHAIN_MODE    
{  
    SHAPE_EQCOMP_SIDECHAIN_MODE_NORMAL,  
    SHAPE_EQCOMP_SIDECHAIN_MODE_INTERNAL,  
    SHAPE_EQCOMP_SIDECHAIN_MODE_EXTERNAL  
}  
```

## 常量

| 常量                                       | 说明    |
| ---------------------------------------- | ----- |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_NORMAL   | 常规模式。 |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_INTERNAL | 内部模式。 |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_EXTERNAL | 外部模式。 |

## 备注

此枚举用于 [GetShapeEqCompSidechainMode](/reference/audio/shapeeqcompcontext/functions/getshapeeqcompsidechainmode) 和 [SetShapeEqCompSidechainMode](/reference/audio/shapeeqcompcontext/functions/setshapeeqcompsidechainmode) 函数。

EQ/压缩器-扩展器模块从一个或两个混合缓冲区获取输入：

* 一个输入是要处理的音频信号。
* 第二个输入称为 *sidechain*，是用于确定音频压缩的可选控制信号。

下图显示了各个模式的处理过程。

**常规、内部和外部模式。**\\
