# GetShapeEqCompExpandMode

> GetShapeEqCompExpandMode

# GetShapeEqCompExpandMode

取得壓縮/擴展模式。

## 語法

```cpp theme={null}
SHAPE_EQCOMP_EXPAND_MODE GetShapeEqCompExpandMode(  
         const SHAPE_EQCOMP_CONTEXT* context  
)  
```

### 參數

*context*   \_In\_\
類型：[SHAPE\_EQCOMP\_CONTEXT\*](/zh-TW/reference/audio/shapeeqcompcontext/structs/shape_eqcomp_context)

指向 `SHAPE_EQCOMP_CONTEXT` 物件的指標。

### 傳回值

類型：[SHAPE\_EQCOMP\_EXPAND\_MODE](/zh-TW/reference/audio/shapeeqcompcontext/enums/shape_eqcomp_expand_mode)

`SHAPE_EQCOMP_EXPAND_MODE` 列舉的成員。

## 備註

一般而言，EQ/壓縮器-擴展器區塊會限制訊號的動態範圍。壓縮器只會作用於超過特定閾值的訊號；低於閾值的訊號會原封不動地通過。

如果此函式的傳回值為 `SHAPE_EQCOMP_EXPAND_MODE_EXPANDER`，則行為會相反：擴展器會作用於低於特定閾值的訊號；高於閾值的訊號會原封不動地通過。

如需詳細資訊，請參閱 [SHAPE 概觀](/zh-TW/build/console-features/audio/overviews/shape-overview) 中的 [等化與壓縮](/zh-TW/build/console-features/audio/overviews/shape-overview#ID4ECF)。

## 需求
