# SetShapeFiltVolMode

设置状态变量滤波器的模式。

## 语法

```cpp theme={null}
HRESULT SetShapeFiltVolMode(  
         SHAPE_FILTVOL_CONTEXT* context,  
         SHAPE_FILTER_MODE ShapeFilterMode  
)  
```

### 参数

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

指向 [SHAPE\_FILTVOL\_CONTEXT](https://docs.xbox.com/zh-CN/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context.md) 对象的指针。

*ShapeFilterMode*   \
类型:[SHAPE\_FILTER\_MODE](https://docs.xbox.com/zh-CN/reference/audio/shapefiltvolcontext/enums/shape_filter_mode.md)

[SHAPE\_FILTER\_MODE](https://docs.xbox.com/zh-CN/reference/audio/shapefiltvolcontext/enums/shape_filter_mode.md) 枚举的一个成员。

### 返回值

类型:HRESULT

HRESULT 成功或错误代码。

## 注解

滤波器/音量(FLTVOL)模块实现为 Chamberlin 滤波器。它提供三种滤波模式(低通、带通和高通)以及一种旁路模式。若要获取当前模式,请使用 [GetShapeFiltVolMode](https://docs.xbox.com/zh-CN/reference/audio/shapefiltvolcontext/functions/getshapefiltvolmode.md)。

其滤波行为设计上与 XAudio2 中的完全一致。

有关详细信息,请参阅 [SHAPE 概述](https://docs.xbox.com/zh-CN/build/console-features/audio/overviews/shape-overview.md) 的 [滤波器/音量模块 (FLTVOL)](https://docs.xbox.com/zh-CN/build/console-features/audio/overviews/shape-overview.md#ID4EBH) 部分。

## 要求

**头文件:** shapefiltvolcontext.h

**支持的平台:** XBOX One 系列主机和 XBOX Series 主机
