# GetShapeEqCompPeakMagnitude

取得峰值量級。

## 語法

```cpp theme={null}
float GetShapeEqCompPeakMagnitude(  
         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：float

峰值量級。

## 備註

每個硬體區塊都會維護兩個 4 位元數字，代表該硬體區塊輸出的量級。量級的計算方式是判斷音訊框架期間的峰值輸出，並計算該峰值絕對值的前導零數目。其中一個 4 位元數字維護持續性的峰值量級，另一個則由硬體在每個音訊框架重設。

如需詳細資訊，請參閱 [SHAPE 概觀](/zh-TW/build/console-features/audio/overviews/shape-overview)中的[溢位、量級與飽和](/zh-TW/build/console-features/audio/overviews/shape-overview#ID4ELAAC)。

## 需求
