Overview
Spectrum background on Song Competition battles. Tab audio only when you enable it on the page; analyzed locally, nothing uploaded.
This extension adds an optional level- or spectrum-style background visualization on Song Competition battle pages. It uses tab audio only after you explicitly turn it on—for example via the extensions menu with “Start levels (this tab)” or the toggle in the on-page panel. Processing happens locally in your browser; no audio is sent to Song Competition or other servers. You can choose how it looks and turn it off anytime. The extension is limited to the official Song Competition sites and does not change other websites.
