LangTube Audio extension

YouTube picks a video's dubbed audio from your account or browser language, and embedded players can't change it. This Chrome extension switches each pane to its own language's audio track and tells the page which languages the video has. It only runs on this site.

1. Unzip it. You get a langtube-audio folder; keep it where it is (Chrome loads it from there).
2. Open chrome://extensions in the address bar.
3. Turn on Developer mode (top right).
4. Click Load unpacked and choose the langtube-audio folder.
5. Reload this page. The header should say “Audio switch on”.

To update: download and unzip again over the same folder, then press the reload (↻) button on the extension's card in chrome://extensions.
