# 音轨分离

使用 ACE Studio 音轨分离将您的歌曲轨道分割为音轨。

## 什么是音轨分离

音轨分离是一款工具，可将包含完整混音的音频片段分割为其核心组成部分的独立轨道，例如歌声、鼓、贝斯和其他乐器。

## 如何使用音轨分离

音轨分离会在时间轴上选定的区域中运行。单击并在画布上拖动以创建选区。请确保该选区覆盖您希望分割的音频片段。

打开音轨分离面板有 3 种方式：

* 点击 **音轨分离** 主工具栏中的图标。
* 选中区域后，右键单击以打开上下文菜单。导航到 AI 工具子菜单并选择 **音轨分离**.
* 点击 <kbd>分割为 Stem</kbd> 音频片段查看器左侧的按钮。有关音频片段的更多信息，请参阅 [片段](/docs/product-wiki-zh/gong-cheng/arrangement-in-canvas/clips.md).

## 分割 Stem

在音轨分离面板中，您需要配置要如何分割音频。

* 选择 4 种音轨分割模式之一：
  * 基础：人声 + 伴奏
  * 专业：人声、鼓、贝斯、钢琴、吉他、其他
  * 高级：所有检测到的 Stem
  * 自定义：描述你想要分离的声音，例如交通、人群、说话声或鸟鸣，音轨分离会将其提取为单独的音轨。
* 移除混响和和声，适用于基础模式和专业模式。

选择音轨分割模式后，点击 <kbd>分割</kbd> 按钮。经过几秒钟的处理后，Stem 将添加到原始轨道下方。

## 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/stem-splitter.md?ask=<question>&goal=<endgoal>
```

`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.
