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/audio_viz.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。

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by ZJU-REAL on GitHub. Read the source before you install it.

Installation

Install the Audio Visualizer AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/ZJU-REAL/Easel.git /tmp/Easel
mkdir -p .claude/skills
cp -r /tmp/Easel/skills/openclaw/audio-visualizer .claude/skills/audio-visualizer
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Audio Visualizer in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Audio Visualizer on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Audio Visualizer is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

音频可视化视频

把音频渲染成带动态波形/频谱的视频，配封面+标题，让纯音频能发到视频平台。全部走 skills/shared/scripts/audio_viz.py，不要手拼 showwaves/showcqt 滤镜。

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
模式否cqt（默认，音乐最好看）/ bars / waves / spectrum
封面否居中封面图（专辑封面/头像/主题图）
标题否顶部标题文字

输出（outputs/主题名/）

  • 可视化视频（*.mp4，音频已嵌入）
  • 报告：模式、时长、画幅

执行步骤

脚本路径（相对项目根）：skills/shared/scripts/audio_viz.py（render -h 看参数）。

bash
# 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

  1. 长音频先用 audio-editing/text-condenser 截出金句片段再可视化，别整集渲染。
  2. 音频原声完整嵌入输出，不重采样丢质量。
  3. 封面图会等比缩放居中，标题自动描边保证可读。
  4. 产物统一进 outputs/主题名/。

参考来源

音频波形/频谱可视化用 ffmpeg showwaves/showfreqs/showspectrum/showcqt，是播客/音频号 上视频平台的标准做法。把各可视化滤镜与封面/标题合成封装成确定性脚本。

Why use Audio Visualizer on TypingMind?

Because you install it once and use it with any model. Audio Visualizer is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Audio Visualizer in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ZJU-REAL/Easel/tree/main/skills/openclaw/audio-visualizer. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Audio Visualizer?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Audio Visualizer?

As many as you like. As long as a model supports skills, you can use Audio Visualizer with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Audio Visualizer AI skill free?

Yes. It is published on GitHub by ZJU-REAL under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
