# GetShapeFiltVolQTarget

取得 Q (品質) 因子目標。

## 語法

```cpp theme={null}
float GetShapeFiltVolQTarget(  
         const SHAPE_FILTVOL_CONTEXT* context  
)  
```

### 參數

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

指向 [SHAPE\_FILTVOL\_CONTEXT](https://docs.xbox.com/zh-TW/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context.md) 物件的指標。

### 傳回值

類型：float

Q 因子目標。

## 備註

濾波器/音量 (FLTVOL) 區塊是以 Chamberlin 濾波器實作。Q 值越大，濾波器的頻寬就越窄。若要變更 Q 目標值，請使用 [SetShapeFiltVolQTarget](https://docs.xbox.com/zh-TW/reference/audio/shapefiltvolcontext/functions/setshapefiltvolqtarget.md)。

濾波行為的設計與 XAudio2 中的濾波行為完全相同。

如需詳細資訊，請參閱 [SHAPE 概觀](https://docs.xbox.com/zh-TW/build/console-features/audio/overviews/shape-overview.md)中的[濾波器/音量區塊 (FLTVOL)](https://docs.xbox.com/zh-TW/build/console-features/audio/overviews/shape-overview.md#ID4EBH) 一節。

## 需求

**標頭：** shapefiltvolcontext.h
