It grabs tab audio via the screen-capture flow and runs it through WebAudio nodes — convolution reverb with selectable IRs, a dB-style bass boost, and playback/pitch controls — all in the browser. Clever, because it sidesteps extension APIs and DRM limitations by using getDisplayMedia, so you get real-time effects on ordinary web players; snagging reliable system/tab audio is the neat technical trick here. Expect some UX friction (you must share the tab and enable 'also share tab audio'), but the core idea is satisfying and immediately usable.
