# GetShapeEqCompMixBufferPeakMagnitude

取得輸出混音緩衝區的峰值量級。

## 語法

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

### 參數

*context*   \_In\_\
類型：[SHAPE\_EQCOMP\_CONTEXT\*](https://docs.xbox.com/zh-TW/reference/audio/shapeeqcompcontext/structs/shape_eqcomp_context.md)

指向 `SHAPE_EQCOMP_CONTEXT` 物件的指標。

### 傳回值

類型：float

峰值量級。

## 備註

除了監視每個個別硬體區塊的峰值量級之外，也會維護混音緩衝區的峰值量級。當硬體區塊的輸出加入混音緩衝區時，峰值量級會以相同方式計算：計算前導零的數目。每個硬體區塊狀態都會另外維護一對 4 位元的峰值量級值。這些值代表硬體區塊的輸出累加到混音緩衝區之後，該混音緩衝區的峰值量級。其中一個 4 位元數字代表持續性的峰值量級，另一個則會在每個音訊框架更新。即使所代表的是混音緩衝區狀態，峰值量級值仍會儲存在 Scalable Hardware Audio Processing Engine (SHAPE) 區塊的內容中。
