# Doubles
使用 Doubles 营造更宽广、更饱满的音效。
## 什么是 Doubles
在人声制作中，我们通常会再录制两条声像向两侧展开的 take，声像范围可设为 50%–100%，与主唱或和声人声一起使用，以获得更宽广的空间感和更饱满的音色。

**为什么不直接复制？**
如果你只是复制，内容会与原始内容完全相同。在这种情况下，AI 会为复制后的内容生成相同的音频结果，这会导致相位问题。
{% endhint %}
## 创建 doubles
在 MIDI 片段或轨道头上右键单击，并在右键菜单中选择“创建人声 Doubles”以打开 Doubles 面板。
在人声 doubles 面板中，你可以
* 设置与原始内容的相似度。100% 表示与原始内容完全不作更改。
* 默认的人性化处理包括音符时长和位置，以及辅音时长
* 85% - 90% 就足以满足常规需求。
* 是否对用户音高应用随机效果。
* 这只会对你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。
* 如果这条轨道上没有混合声线，你就不需要勾选此框。

## 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.
