Umbra EQ — Equalizer & Bass Boost

About

Umbra EQ adds a real equalizer to any browser tab.

• 11-band parametric EQ. Drag the response curve to boost or cut any frequency, live, while the audio plays, with a spectrum analyzer behind it so you see exactly what you are shaping.
• Per-tab EQ. Every tab gets its own equalizer, so a movie tab and a music tab can sound different at the same time.
• Remembers your sound per website and re-applies it automatically the next time you open that site.
• Site rules. Point a preset at sites by an address pattern, for example one rule that covers a movie site and all of its mirrors.
• Presets. Save your own, and share your presets or rules with a single copy-paste code, or an export file.
• Master volume boost when a video is too quiet, plus one-click bass boost.
• Русский and English interface, four themes and a custom accent color.
• Works on any tab with sound: music, video, streams, calls.
• Everything runs on your computer. Umbra never records or sends your audio, and there is no account to sign up for.

How to use:
1. Play audio in a tab.
2. Click the Umbra EQ icon, then "EQ This Tab".
3. Drag a dot: left and right is frequency, up and down is boost or cut. Shift-drag changes the width, double-click resets a band.
4. Open the same site again and your sound comes back automatically. Add pattern rules in the Rules tab to cover a whole site or several at once.
