What it does
Audio Editing is an agent skill from ZJU-REAL/Easel. 通用音频处理：音频剪辑/裁剪、格式转码（mp3/wav/m4a/aac）、音量归一化、从视频提取音轨、多段拼接、淡入淡出、变速（保音高）。当用户说“剪音频”“裁一段”“转成 mp3”“调音量/响度”“提取音轨/扒音频”“拼接音频”“淡入淡出”“加速/减速音频”“变速不变调”时使用。与 audio-denoise 的区别：audio-denoise 专做降噪，audio-editing 做除降噪外的通用音频操作（也内置 denoise 作为兜底）。
Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `EASEL-META.md`).
It sits in Media & Creative, covering Music and audio generation. It works with FFmpeg. The repository describes itself as: An open-source AI agent for social media — discover trends, create content, publish everywhere, and learn what works across Xiaohongshu, Douyin, Zhihu, Bilibili, and more.🎨一个开源的… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Music and audio generation
Example prompts
- “转成 mp3”
- “调音量/响度”
- “提取音轨/扒音频”
- “/audio-editing”
Requirements
- Python 3
Workflow steps
9 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 278f420. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audio Editing loads about 753 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 143 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

通用音频处理
除降噪外的通用音频操作：裁剪、转码、音量归一化、提取音轨、拼接、淡入淡出、变速。全部通过共享脚本 skills/shared/scripts/audio_ops.py 封装 ffmpeg，参数确定、可复现，不现场手拼命令。
输入
| 字段 | 必填 | 说明 |
|---|---|---|
| input_file | 是 | 音频或视频文件路径 |
| operation | 是 | trim / convert / normalize / extract / concat / fade / speed / denoise / info |
| output_file | 否 | 默认 outputs/主题名/{name}-{op}.{ext} |
支持格式：wav / mp3 / m4a / aac / flac，视频容器 mp4 / mkv / mov（提取音轨）。
输出
- 处理后的音频文件（放入
outputs/主题名/） - 每次操作打印实际执行的 ffmpeg 命令 + 输出文件的时长/码率/声道/采样率
执行步骤
脚本路径（相对项目根）：skills/shared/scripts/audio_ops.py。每个子命令都支持 -h。
0. 环境检查 + 探测
python skills/shared/scripts/audio_ops.py info input.mp3脚本自身会检查 ffmpeg/ffprobe，缺失时给安装提示。先 info 展示文件时长/码率/声道再动手。
1. 裁剪 trim
# 起止时间
python skills/shared/scripts/audio_ops.py trim in.mp3 -o outputs/主题名/clip.mp3 --start 00:00:05 --end 00:00:20
# 起点 + 时长
python skills/shared/scripts/audio_ops.py trim in.mp3 -o clip.mp3 --start 5 --duration 152. 转码 convert
python skills/shared/scripts/audio_ops.py convert in.wav -o out.mp3 --bitrate 192k
python skills/shared/scripts/audio_ops.py convert in.m4a -o out.wav --sample-rate 44100 --channels 2输出格式由扩展名决定（mp3/wav/m4a/aac）。
3. 音量归一化 normalize
python skills/shared/scripts/audio_ops.py normalize in.mp3 -o out.mp3默认 loudnorm 到 -14 LUFS / -1.5 dBTP（社媒/播客通用响度）。可用 --i --tp --lra 覆盖。
4. 提取音轨 extract
python skills/shared/scripts/audio_ops.py extract video.mp4 -o audio.m4a
python skills/shared/scripts/audio_ops.py extract video.mp4 -o audio.aac --copy # 不重编码，最快5. 拼接 concat
python skills/shared/scripts/audio_ops.py concat a.mp3 b.mp3 c.mp3 -o all.mp3按参数顺序拼接，重编码方式兼容不同采样率/容器。
6. 淡入淡出 fade
python skills/shared/scripts/audio_ops.py fade in.mp3 -o out.mp3 --fade-in 2 --fade-out 3--fade-out 自动定位到结尾前 N 秒。
7. 变速 speed（保持音高）
python skills/shared/scripts/audio_ops.py speed in.mp3 -o out.mp3 --factor 1.5 # 1.5 倍速
python skills/shared/scripts/audio_ops.py speed in.mp3 -o out.mp3 --factor 0.8 # 放慢基于 atempo 保音高，超 0.5-2.0 范围自动级联。
8. 降噪 denoise（兜底，专项请用 audio-denoise）
python skills/shared/scripts/audio_ops.py denoise in.wav -o out.wav --tier 2与 audio-denoise 的边界
- audio-denoise：降噪专项 SKILL，负责选级、模型下载、降噪报告等完整流程——需要认真降噪时用它。
- audio-editing：通用音频处理。
denoise子命令仅作为顺手兜底，两者调用同一个audio_ops.py denoise，能力一致，定位不同。
规则
- 绝不删除原始文件 — 只写新文件到
outputs/主题名/。 - 先 info 再处理 — 展示文件信息，避免误操作。
- 视频输入只动音频 — denoise 对视频自动
-c:v copy；纯抽音用 extract。 - 透明执行 — 脚本会打印实际 ffmpeg 命令。
- 无 Profile 也能用 — 音频处理不依赖账号画像。
Profile 感知
有 Profile 时可据平台偏好选默认参数（如短视频响度、目标码率）；无 Profile 退到通用默认（-14 LUFS、192k）。

Can I use Audio Editing in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ZJU-REAL/Easel --skill audio-editing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/audio-editing, .gemini/skills/audio-editing, .github/skills/audio-editing and .opencode/skills/audio-editing in your project.
What does Audio Editing need to run?
Going by SKILL.md and its folder, Audio Editing needs the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Audio Editing access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
