Browser Audio Capture

Give any AI agent ears for the browser. One Chrome extension captures audio from any tab — meetings, YouTube, podcasts, webinars, courses, earnings calls — and streams it to your AI pipeline.

Why Use This

Your AI agent can't hear anything happening in your browser. This skill fixes that. Capture audio from any Chrome tab and stream it to your agent — no API keys, no OAuth, no per-platform integrations.

Use cases: meeting summaries, YouTube/podcast notes, competitive intel from earnings calls, auto-notes from online courses, customer call analysis — anything that plays audio in a browser tab.

Works with any AI agent — Claude, ChatGPT, OpenClaw, LangChain, CrewAI, or your own. If your agent can run shell commands or receive HTTP, it gets browser audio.

Prerequisites

Chrome with remote debugging:

# macOS
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --remote-debugging-port=9222 --user-data-dir=$HOME/.chrome-debug-profile &

Python 3.9+ with aiohttp: pip install aiohttp

Quick Start

CLI (any agent that can exec)

# List tabs — meetings flagged with 🎙️
python3 -m browser_capture.cli tabs

# Auto-detect and capture meeting tab
python3 -m browser_capture.cli capture

# Continuous watch mode
python3 -m browser_capture.cli watch --interval 15

# Stop
python3 -m browser_capture.cli stop

Chrome Extension (one-click, persistent)

1. chrome://extensions/ → Developer mode → Load unpacked → scripts/extension/
2. Join a meeting → click Percept icon → Start Capturing
3. Close popup — capture continues in background

Supported Platforms

Google Meet • Zoom (web) • Microsoft Teams • Webex • Whereby • Around • Cal.com • Riverside • StreamYard • Ping • Daily.co • Jitsi • Discord — plus any future platform that runs in a browser.

Audio Output

Streams to http://127.0.0.1:8900/audio/browser as JSON:

{
  "sessionId": "browser_1709234567890",
  "audio": "<base64 PCM16>",
  "sampleRate": 16000,
  "format": "pcm16",
  "tabUrl": "https://meet.google.com/...",
  "tabTitle": "Weekly Standup"
}

Configure endpoint in scripts/extension/offscreen.js (PERCEPT_URL). Point it at Whisper, Deepgram, NVIDIA Riva, or any transcription service.

Troubleshooting

• No tabs: Chrome needs --remote-debugging-port=9222
• Button won't click: Remove + re-add extension (MV3 caches aggressively)
• Audio not arriving: Check receiver on port 8900. Extension sends to /audio/browser

整體質量不錯，功能實用，文件清晰易讀。CLI和瀏覽器擴充套件兩種方式都很好用，自動檢測會議功能很方便。不足的是安裝Chrome擴充套件時可能會提示缺少圖示檔案，部分網站可能無法正常捕獲音訊。建議等待作者修復這些問題後再使用。
