# SetShapeFiltVolFrequency

設定 FLTVOL 內容的轉角頻率。

## 語法

```cpp theme={null}
HRESULT SetShapeFiltVolFrequency(  
         SHAPE_FILTVOL_CONTEXT* context,  
         float frequency  
)  
```

### 參數

*context*   \_Inout\_\
類型：[SHAPE\_FILTVOL\_CONTEXT](/zh-TW/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context)\*

指向 [SHAPE\_FILTVOL\_CONTEXT](/zh-TW/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) 物件的指標。

*frequency*   \
類型：float

轉角頻率。必須介於 0-7999 Hz 的範圍內。

### 傳回值

類型：HRESULT

HRESULT 成功或錯誤碼。

## 備註

濾波器/音量 (FLTVOL) 區塊是以 Chamberlin 濾波器實作。若要取得目前的轉角頻率，請使用 [GetShapeFiltVolFrequency](/zh-TW/reference/audio/shapefiltvolcontext/functions/getshapefiltvolfrequency)。

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](/zh-TW/build/console-features/audio/overviews/shape-overview)中的[濾波器/音量區塊 (FLTVOL)](/zh-TW/build/console-features/audio/overviews/shape-overview#ID4EBH) 一節。

## 需求

**標頭：** shapefiltvolcontext.h

**支援的平台：** XBOX One 系列主機與 XBOX Series 主機
