Even Keel - Audio Pro

32-band EQ, 6-band parametric EQ, stereo expander, compressor, limiter and automatic loudness leveling for any web audio/video.

Even Keel - Audio Pro puts a full audio toolkit on the web pages where you listen: YouTube, streaming sites, podcasts, news streams and more. THREE WAYS TO USE IT - Simple: a tiny window with one volume slider (0-500%) and an Enhance switch. It starts by itself when a page plays sound, stays on after reloads and restarts, and has a Skip site button for sites you want left alone. - Compact: presets and the main controls in a small window. - Full: every control, the live spectrum and the response curve. - One shared sound: all three views play the same preset and settings, and switching between them keeps the audio playing without a gap. START WITH A PRESET - Pick one of 32 ready-made presets covering music styles, speech, movies, late-night listening and classic radio sounds. Every preset is level-matched, so switching never makes it jump louder. - Click Enable. That's it. - Auto-Normalize keeps loud and quiet songs at an even level, so you stop reaching for the volume knob. A Density slider adds a little punch to older, quieter masters. - Hiss Guard keeps the leveler from raising tape hiss and room noise in the quiet gaps of old recordings. - Listening on: tell it what you are listening on (open-back or closed-back headphones, computer speakers, theater, studio or hi-fi) and it adds a gentle matching correction, with a Strength setting and optional cross-feed. Click the same tile again and the stage is removed completely. FAIR COMPARISONS - Bypass button for an instant before/after, with optional A/B level match so louder doesn't fool your ears. Off by default. - Mono and Balance controls, and a clear warning when the volume is set high. GO DEEPER WHEN YOU WANT TO ("Advanced controls") - 32-band graphic EQ and 6-band parametric EQ with a live response curve, plus an EQ gain slider (plus or minus 12 dB) - Compressor (single or three-band multiband) and limiter with safe, ready-made settings, gain-reduction meters, and a soft safety stage with 2x oversampling - A five-dial Make-up EQ after the compressor (Low Boost, Low Atten, Mid, Presence, Air) - Stereo expander (width) with bass mono, for a bigger sound stage - Ten slots to save your own presets - 31 colour themes from the view menu (Classic is the default), including retro media-player styles, with optional background art. MORE THAN ONE TAB? - The Tabs menu lists every tab that is playing sound. Control any of them, or apply the same settings to all of them with one click. GOOD TO KNOW - It works on the audio and video players that pages show directly. Players inside embedded frames, pages that already run their own Web Audio, and audio files a page loads from another website without permission (the browser would silence them) are left alone. Calls and camera streams are left alone on purpose. PRIVATE BY DESIGN - No tracking, tracing, fingerprinting, analytics, ads or usage reporting. Ever. - The extension makes no network connections of its own and sends nothing anywhere. - Your settings are stored only in your own browser. - It never stores or sends your browsing history, page content or audio. It reads a tab's title and site name only to list tabs in its own window, and it analyses the sound only on your computer, to drive its meters and leveler. FREE, WITH AN OPTIONAL DONATE BUTTON - Everything works the same whether or not you donate. The Donate button is just a link that opens the developer's PayPal page in a new tab when you click it.
