LUFS-based tab volume balancer for Chrome

LUFS-based tab volume balancer for Chrome Changelog v1.1.2 - Improved implementation to require fewer permissions - Improve icon display --- v1.1.1 - Improved output limiter to the mixer stage instead of per-channel - Configurable auto-focus gain --- v1.1.0 ## New features - **Focus and auto-focus:** Keep one monitored tab prominent while lowering the others by 12 dB. Auto-focus follows the active monitored tab. - **Automatic balancing on capture:** Registering a tab now starts loudness balancing automatically. - **Browser tab ordering:** Monitored tabs follow their order within browser windows and update when tabs move. ## Fixes - Correct LUFS sample-rate handling and K-weighting coefficients, with consistent mono and multichannel processing. - Correct the organization link in the popup footer. ## Performance and interface improvements - Move the real-time LUFS analysis kernel to Rust and WebAssembly, optimize loudness gating in the power domain, and reduce copying across the audio bridge. - Share the offscreen audio engine across captures and batch incremental meter updates to reduce repeated work and messaging. - Throttle real-time control updates and smooth automatic gain changes. - Refactor the popup into reusable controls with UnoCSS and trim the production bundle. --- v1.0.5 - Added collapsible tab cards with smoother transitions for more compact multi-tab sessions. - Language selection now persists between popup sessions. - Reworked audio-session coordination: the offscreen document now owns live capture and auto-balancing state, while the background service worker focuses on permissions and lifecycle events. - Replaced popup polling with an initial snapshot followed by live updates. - Applied continuous auto-balancing directly alongside LUFS updates. - Made capture startup and cleanup deterministic across tab closure, navigation, stream termination, and concurrent stop events. - Preserved each tab’s configured gain when entering or leaving solo mode. - Serialized settings updates to prevent rapid changes from overwriting newer values. - Reduced redundant gain operations and optimized LUFS calculations. - Simplified auto-balance controls by removing the one-shot balance action. - Fixed audio capture and processing resources remaining alive after tabs stopped or navigated. - Fixed solo mode overwriting saved gain or leaving tabs at unintended levels. - Fixed races between popup updates, settings persistence, and simultaneous cleanup events. - Improved handling of invalid persisted settings and non-finite loudness values. --- v1.0.4 - Fix Simplified Chinese translation --- v1.0.3 - Fix Logo display --- v1.0.2 - Update the reference loudness algorithm to ITU-R BS.1770-5 - Add i18n support - Improve performance and fix a memory leak issue - Improve UI --- v1.0.1 - Initial release
