# SetShapeEqCompCompressorMode

> SetShapeEqCompCompressorMode

# SetShapeEqCompCompressorMode

设置压缩模式。

## 语法

```cpp theme={null}
HRESULT SetShapeEqCompCompressorMode(  
         SHAPE_EQCOMP_CONTEXT* context,  
         SHAPE_EQCOMP_COMPRESSOR_MODE mode  
)  
```

### 参数

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

指向 SHAPE\_EQCOMP\_CONTEXT 对象的指针。

*mode*   \
类型：[SHAPE\_EQCOMP\_COMPRESSOR\_MODE](/reference/audio/shapeeqcompcontext/enums/shape_eqcomp_compressor_mode)

SHAPE\_EQCOMP\_COMPRESSOR\_MODE 枚举的一个成员。

### 返回值

类型：HRESULT

HRESULT 成功或错误代码。

## 备注

在常规模式下，输入电平是瞬时的，对每个采样都会计算压缩。在 RMS 模式下，则使用前 128 个采样的滑动平均值（代表 RMS 值的近似值）作为输入电平，而不是当前输入采样的绝对电平。（滑动平均值是 RMS 值的近似值。）

有关详细信息，请参阅 [SHAPE 概述](/build/console-features/audio/overviews/shape-overview) 中的 [均衡与压缩](/build/console-features/audio/overviews/shape-overview#ID4ECF)。
