Data and privacy
Audio is processed locally with Web Audio. No recording, uploads, or microphone capture. The extension captures a tab’s audio only after a user action.
Limitations
High gain can distort audio and harm hearing. Protected media may not work. Processing can add latency or conflict with other capture extensions. Active streams do not survive a browser restart.
