# 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: ```bash # 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) ```bash # 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: ```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`
