use

1. open a YouTube video page
2. click the extension icon
3. set playback speed

5. optional: choose the mic source from Mic, then click Auto to estimate delay from speaker output. Keep the popup open, allow mic access, and keep the selected mic near the speaker until calibration finishes.

troubleshooting

• If auto calibration says the mic is blocked after reloading or moving the unpacked extension, open the extension's details page in Chrome, go to Site settings, allow Microphone, and retry. Chrome treats each extension ID as a separate site permission origin.
