YouTube Audio Only

About

🎧 YouTube Audio Only — Stream the sound, skip the video.

Play any YouTube video in audio-only mode and save up to 80% of your 
bandwidth — without losing a single bit of audio quality.

YouTube already streams audio and video as two completely separate 
tracks. This extension simply tells Chrome to block the video track 
before it ever downloads. Your audio arrives at full quality (Opus/AAC), 
exactly as if you were watching in 4K.

── WHAT IT DOES ──────────────────────────
✔ Blocks YouTube's video stream at the network level
✔ Audio plays at full quality — Opus or AAC, untouched
✔ Saves ~80% bandwidth per minute of playback
✔ Video frame goes black — nothing else changes
✔ Works on all YouTube videos, playlists, and live streams

── TWO WAYS TO TOGGLE ────────────────────
① Click the 🎧 toolbar icon → flip the switch → reload tab
② Use the headphone button injected directly into the YouTube player

── PERFECT FOR ───────────────────────────
- Background listening (podcasts, music, lectures)
- Slow or metered internet connections
- Saving mobile hotspot data
- Countries with limited bandwidth

── PRIVACY ───────────────────────────────
No data is collected, stored, or transmitted. The extension works 
entirely offline using Chrome's built-in declarativeNetRequest API. 
No account required. No ads. No tracking.

── TECHNICAL ─────────────────────────────
Built with Manifest V3. Uses declarativeNetRequest to block requests 
matching YouTube's video-only DASH segment URLs on googlevideo.com. 
Your toggle preference is saved locally in chrome storage.
