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 any web page that plays sound: 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 on any page that 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 never interrupts the audio, not even for a moment. 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. - 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 headphone 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 and limiter with safe, ready-made settings, and a soft safety stage with 2x oversampling - Low, Mid and High tone make-up dials after the limiter - Stereo expander (width) with bass-mono, for a bigger sound stage - Five 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. 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 does not read or store your browsing history, page content, or your audio. 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.
