# GetShapeFiltVolDelay2

获取低通延迟。

## 语法

```cpp theme={null}
float GetShapeFiltVolDelay2(  
         const SHAPE_FILTVOL_CONTEXT* context  
)  
```

### 参数

*context*   \_In\_\
类型:[SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context)\*

指向 [SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) 对象的指针。

### 返回值

类型:float

低通延迟。

## 注解

此函数从指定的 [SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) 对象获取低通延迟的当前值。

若要获取带通延迟,请使用 [GetShapeFiltVolDelay1](/reference/audio/shapefiltvolcontext/functions/getshapefiltvoldelay1) 函数。

有关详细信息,请参阅 [SHAPE 概述](/build/console-features/audio/overviews/shape-overview) 的 [滤波器/音量模块 (FLTVOL)](/build/console-features/audio/overviews/shape-overview#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
