# GetShapeSrcPeakMagnitude1

获取右声道的峰值幅度。

## 语法

```cpp theme={null}
float GetShapeSrcPeakMagnitude1(  
         const SHAPE_SRC_CONTEXT* context  
)  
```

### 参数

*context*   \_In\_\
类型：[SHAPE\_SRC\_CONTEXT](/reference/audio/shapesrccontext/structs/shape_src_context)\*

指向 [SHAPE\_SRC\_CONTEXT](/reference/audio/shapesrccontext/structs/shape_src_context) 对象的指针。

### 返回值

类型：float

峰值幅度。

## 备注

每个硬件块维护两个 4 位数字，表示硬件块输出的幅度。幅度通过确定音频帧期间的峰值输出以及计算该峰值绝对值的前导零来计算。一个 4 位数字维护持久的峰值幅度，另一个由硬件在每个音频帧重置。

有关更多信息，请参阅 [SHAPE 概述](/build/console-features/audio/overviews/shape-overview)中的[溢出、幅度和饱和](/build/console-features/audio/overviews/shape-overview#ID4ELAAC)。

## 要求

**标头：** shapesrccontext.h

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