Dual-Band Compressor

Per-tab two-band audio compressor with in-page processing, preserving media keys. Dual‑Band Compressor brings studio‑style dynamic range control to browser audio, taming loud spikes and lifting quiet voices so streams, video calls, and music are consistently clear. With a simple popup, create presets, map them per site or page, and toggle processing on demand—no accounts, tracking, or remote code. Built on Manifest V3 with revolutionary in‑page processing, it runs efficiently on all websites and keeps data on the device. NEW in v1.5.0: Universal compatibility, popout controls, keyboard shortcuts, and auto‑initialization What it does • Smooths volume with two‑band compression for transparent control of lows and highs, reducing fatigue while preserving detail. • Boosts intelligibility of dialogue, podcasts, and lectures without clipping by combining attack/release controls, crossover, blend, and makeup gain. • Applies the right sound automatically using per‑site or per‑page mappings, with instant switching as tabs change and auto‑start on page loads. • Opens a popout window for persistent controls that scale perfectly to any zoom level and stay on top while you work. • Responds to global keyboard shortcuts you configure for instant compression toggle and popout access without opening menus. • Saves preferences to Chrome's storage so presets sync across profiles when enabled. Why install it • Hear content the way it should sound: fewer jolts from ads and sudden effects, more consistent levels across videos, streams, and calls. • Works everywhere: YouTube, Netflix, Twitch, video calls, podcasts—no more sites where compression mysteriously fails. • Designed for focus and productivity: quick enable/disable, popout controls, fine‑grained sliders, and log‑scaled timing for precise feel. • Private by default: processes audio locally using direct web integration; no external servers, accounts, or hidden network requests. How it works • Integrates directly with media elements on the page using Web Audio API, eliminating compatibility issues and permission overhead. • Uses minimal permissions: standard extension access, storage for presets, and scripting for in‑page audio processing. • Maintains full media key functionality while adding transparent compression layer between source and speakers. Getting started • Install, open a tab with audio, click the toolbar button, pick "Default" or create a preset, then map it to the current site for automatic activation next time. • Set keyboard shortcuts in chrome://extensions/shortcuts for instant control from anywhere. • Click "Popout" for persistent controls that stay visible while you browse other tabs or applications.
