# GetShapeSrcPitch

获取音调。

## 语法

```cpp theme={null}
float GetShapeSrcPitch(  
         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

音调。

## 备注

采样率转换器 (SRC) 块读取 PCM 样本并执行采样率转换和音调移位。音调和音调目标值的取值范围为 0.0625-3.99。若要更改音调，请使用 [SetShapeSrcPitch](/reference/audio/shapesrccontext/functions/setshapesrcpitch)。

有关 SRC 的更多信息，请参阅 [SHAPE 概述](/build/console-features/audio/overviews/shape-overview)中的[采样率转换器 (SRC) 块](/build/console-features/audio/overviews/shape-overview#ID4EOE)。

## 要求
