# SHAPE\_FLOWGRAPH\_COMMAND

Shape 流图命令（联合体）。

## 语法

```cpp theme={null}
union SHAPE_FLOWGRAPH_COMMAND {  
    UINT64 entry;  
    SHAPE_FLOWGRAPH_COMMAND_HEADER header;  
    SHAPE_FLOWGRAPH_ALLOC_MIXBUFFER_COMMAND allocMixBuffer;  
    SHAPE_FLOWGRAPH_SRC_COMMAND src;  
    SHAPE_FLOWGRAPH_EQCOMP_COMMAND eqComp;  
    SHAPE_FLOWGRAPH_FILTVOL_COMMAND filtVol;  
    SHAPE_FLOWGRAPH_DMA_COMMAND dma;  
}  
```

## 备注

为了使用可伸缩硬件音频处理 (SHAPE)，游戏通常会创建一个 SHAPE 流图。有关更多信息，请参阅 [ACP 概述](/build/console-features/audio/overviews/acp-overview) 中的 XMA 实用工具部分。SHAPE 流图是一个命令数组（每个 SHAPE 块一个命令）和随附的上下文数据，实际上描述了各个块的操作顺序以及它们所操作的数据。ACP（音频控制处理器）使用流图中的数据来正确调度 SHAPE 块内的操作。

发送到 SHAPE 硬件进行处理的命令列表称为流图。

执行列表是由 SHAPE 音频处理器处理的元命令列表。由于 SHAPE 音频处理器是可编程且灵活的，因此执行列表的格式和功能也是灵活的。某些元命令具有隐式数据，而其他元命令具有显式参数。这些元命令还通过使用混音缓冲区指定特定的 SHAPE 硬件块从何处获取输入以及将输出写入何处。混音缓冲区由硬件分配。

## 要求
