About Universal LUFS Monitor

This extension is a developer tool designed to analyze the audio loudness (LUFS) of web-based games and multimedia applications. Reason for <all_urls>: 1. Dynamic Hosting Environments: Web games are often hosted on unpredictable domains, including dynamic cloud URLs, internal staging servers (localhost, 192.168.x.x), or third-party game portals. We cannot pre-define a specific list of domains. 2. AudioContext Injection: To measure audio levels, the extension must inject a content script to attach an AnalyzerNode to the page's AudioContext. This must happen on whichever page the game is running. Privacy Note: - This extension DOES NOT collect, store, or transmit any user browsing history or personal data. - It strictly interacts only with the Web Audio API objects to calculate mathematical RMS values locally within the browser.
