Broadcast-style processing for every tab.

Even Keel – Audio Pro brings a full broadcast processing chain to Chrome, Brave and Edge. Loud ads stop blasting, quiet videos come up, and streams sound the way radio is supposed to. Use the one-click popup, or open the full rack and patch it the way you like.

What it does

Auto-normalize

A LUFS-based leveler holds everything near your target (−14 LUFS by default), so tab-to-tab volume stays even.

Volume to 500%

Boost very quiet sources well past 100%. A brickwall limiter and soft safety stage catch the peaks.

40+ presets

Genre presets from Pop to Classical, plus radio flavors: AM, FM, FM HD and HD2. Save up to 10 of your own.

Listening On

Tune the sound for open-back or closed-back headphones, computer speakers, theater, studio monitors or hi-fi, with optional crossfeed.

Full processing chain

32-band graphic and 6-band parametric EQ, single or multiband compressor, Hiss Guard, stereo expander and a Neve/Pultec-style make-up EQ.

A/B match & themes

Equal-loudness A/B for fair comparisons, Simple, Compact or Full views, and themes from Walnut Lounge to Cyberpunk.
