Edit audio files by trimming sections, converting formats, matching loudness, or extracting sound from videos. You can also join recordings, add fades, and change playback speed while keeping the original pitch.

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）。
安装前可以查看交给 AI 代理的指令内容。
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。
| 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）。
outputs/主题名/）脚本路径（相对项目根）：skills/shared/scripts/audio_ops.py。每个子命令都支持 -h。
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。
# 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
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）。
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。
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
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。
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。
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。
python skills/shared/scripts/audio_ops.py denoise in.wav -o out.wav --tier 2
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。outputs/主题名/。-c:v copy；纯抽音用 extract。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）。
