# Doubles
## 什么是 Doubles
在人声制作中，我们通常会额外录制两条声部，将其声像设置在 50%–100% 的两侧，并与主唱人声或和声人声搭配，以获得更宽广的空间感和更饱满的效果。

**为什么不直接复制？**
如果只是复制，内容将与原始内容完全相同。在这种情况下，AI 会为复制内容生成相同的音频结果，从而导致相位问题。
{% endhint %}
## 创建 doubles
右键单击 MIDI 片段或轨道标题，在右键菜单中选择“创建人声 doubles”，即可打开 Doubles 面板。
在人声 doubles 面板中，您可以
* 设置与原始内容的相似度。100% 表示不对原始内容进行任何更改。
* 默认的人性化处理包括音符的音符时长和位置，以及辅音的音符时长
* 对于常规需求，85%–90% 已足够。
* 是否对用户绘制的音高应用随机效果。
* 这仅对您绘制的音高曲线生效。勾选此复选框不会改变 AI 生成的默认音高。
* 是否对 VoiceMix 应用随机效果。
* 如果您尚未在此轨道上混合声线，则无需勾选此框。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.acestudio.ai/docs/product-wiki-zh/ai-gong-ju/doubles.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
