Tab Qualizer

Capture and process tab audio with real-time DSP controls.

Tab Qualizer — real-time audio control for any Chrome tab Listen to YouTube, Spotify, podcasts, or any site with audio — and adjust the sound without leaving the page. Tab Qualizer captures the active tab’s audio, processes it in real time, and plays it back through your speakers with the settings you choose. What you can do 3-band equalizer — boost or cut low, mid, and high frequencies independently Gain control — make quiet tabs louder or tame hot sources (up to 250%) Vocal reduction — two approaches, so you can pick what works best for each track One-click presets — start from Flat, Karaoke, Podcast, or Bass Boost and fine-tune from there Two vocal-removal methods Most vocal tools use a single trick. Tab Qualizer gives you a choice: Method Best for - Freq Frequency-based reduction. Attenuates centered vocals in the low, mid, and high bands. Often cleaner on busy mixes where phase tricks add artifacts. Used by Karaoke 2. - F+Ph (Freq + Phase) Same band-based reduction, plus phase cancellation (L−R) to suppress center-panned vocals. Stronger on classic stereo mixes with vocals in the middle. Used by Karaoke 1. Adjust strength to dial reduction up or down. With F+Ph, you can also flip phase direction (L−R / R−L) when a track needs it. Results depend on how the source was mixed — no tool removes vocals perfectly on every song. Presets Flat — neutral starting point Karaoke 1 — F+Ph vocal reduction, strong bass lift, ready for sing-along Karaoke 2 — Freq-only reduction, mid scoop + high lift, full strength Podcast — clearer speech: mid boost, gentle low cut Bass Boost — extra low end for music and videos How it works Open a tab with audio Click the Tab Qualizer icon → Start Pick a preset or adjust EQ, gain, and vocal settings live Click Stop when you’re done Chrome mutes the original tab while capturing; you hear the processed version through the extension.
