AOWL Active Tab Watermark Decoder

AOWL Active Tab Watermark Decoder detects AOWL/CryptoWatermark metadata from audio playing in the active browser tab.

After you click the extension icon, the extension opens a small live decoding window and listens to audio from the selected active tab. Audio is processed locally in your browser to detect embedded watermark signals. When a watermark is detected, the extension verifies the detected watermark with the AOWL backend and displays public metadata such as the media title, detected watermark ID, ownership information, and related public links.

This extension is intended for users who need to verify whether audio or video playback contains AOWL/CryptoWatermark metadata.

Key features:

- Starts only after you click the extension icon

- Captures audio from the active tab for watermark detection
