What it does
Audio Visualizer is an agent skill from ZJU-REAL/Easel. 音频可视化视频：把纯音频（播客片段、音乐、口播金句、电台）渲染成带动态波形/频谱的视频，配封面和标题，好发到抖音/B站/视频号等只收视频的平台。当用户说 音频可视化、音频转视频、播客做成视频、音频波形视频、音乐可视化、给音频配画面、声波视频、频谱视频、把音频发到视频平台、电台切片视频 时使用。基于 shared/scripts/audioviz.py（ffmpeg showwaves/showcqt/showspectrum）。与 audio-mix 区别：那个输出音频，本 SKILL 输出视频；与 slideshow-video 区别：那个用图片，本 SKILL 用音频驱动画面。
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Video production. 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 Video production
Example prompts
- “/audio-visualizer”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 长音频先用 audio-editing/text-condenser 截出金句片段再可视化，别整集渲染。
- 音频原声完整嵌入输出，不重采样丢质量。
- 封面图会等比缩放居中，标题自动描边保证可读。
- 产物统一进 outputs/主题名/。
What it can do on your machine
Read from SKILL.md and the folder at commit 5e0ccc1. 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 Visualizer loads about 542 tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 89 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.

输出音频（混音）见 audio-mix；用图片做视频见 slideshow-video； 给已有视频加字幕见 auto-subtitle。
输入
| 字段 | 必填 | 说明 |
|---|---|---|
| 音频文件 | 是 | 播客/音乐/口播片段（没给就问） |
| 画幅 | 是 | 用户或上游任务未明确横版/竖版（或具体分辨率）时，制作前必须追问并等确认；不得按平台、Profile 或默认值静默推断，已明确则不重复问 |

执行步骤
脚本路径（相对项目根）：skills/shared/scripts/audio_viz.py（render -h 看参数）。
# 音乐/金句：CQT 音乐频谱（随音符跳动，最好看）
python skills/shared/scripts/audio_viz.py render -i clip.mp3 \
-o outputs/主题名/out.mp4 --mode cqt --title "本期金句" --cover cover.jpg
# 播客口播：底部波形条 + 封面
python skills/shared/scripts/audio_viz.py render -i podcast.mp3 \
-o outputs/主题名/out.mp4 --mode waves --cover avatar.png --size 1080x1920
# 律动柱状 / 滚动声谱
python skills/shared/scripts/audio_viz.py render -i song.mp3 -o out.mp4 --mode bars
python skills/shared/scripts/audio_viz.py render -i song.mp3 -o out.mp4 --mode spectrum模式怎么选
| 模式 | 观感 | 适用 |
|---|---|---|
cqt | 全屏音符频谱，随旋律跳动 | 音乐、有旋律的内容（默认） |
bars | 底部频谱柱，律动感强 | 音乐、卡点、电台 |
waves | 底部波形线，简洁干净 | 播客、口播、访谈 |
spectrum | 全屏滚动声谱图，科技感 | 电子/科技类、氛围 |
--bg-image 换背景图，--color 换背景色，--wave-color 换波形颜色。
Profile 感知
- 有 Profile：
platforms.md只用于给出画幅建议，仍须用户确认；标题/封面风格贴合账号； 播客/口播账号默认waves，音乐账号默认cqt/bars。 - 无 Profile：先确认横版/竖版；默认 cqt 模式。
规则
- 长音频先用 audio-editing/text-condenser 截出金句片段再可视化，别整集渲染。
- 音频原声完整嵌入输出，不重采样丢质量。
- 封面图会等比缩放居中，标题自动描边保证可读。
- 产物统一进
