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）。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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
```bash
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
```bash
# 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 15
```
### 2. 转码 convert
```bash
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
```

How to install
mdr add zju-real/easel/audio-editing@sha256:96869103fe5d1835The line at the top of this page pins the label git:20261012.0d53744, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
