Tapdeck

Real-time audio processing for any tab: parametric EQ, compressors, limiter, denoise, auto-level and more, with live visualization.

Tapdeck is an open source extension that puts a real audio processing rack on any browser tab. Start it on a tab and its sound runs through whatever chain you build before it reaches your speakers: a parametric EQ you drag on a live spectrum, a compressor, a multiband compressor, a gate, a limiter, a saturator, a transient shaper, a noise suppressor, a de-reverb, an auto-leveler, and a stereo utility with headphone crossfeed. Reorder modules by dragging, bypass any of them, and watch the meters move. Each tab gets its own rack, so a film in one tab and a call in another can have different settings at the same time. Everything runs inside the extension with the Web Audio API. There is no companion app, no system audio routing, no account, and nothing is sent anywhere. The only network request is fetching a headphone profile from the AutoEq repository when you ask for one.
