Real-Time Web Audio Inspector + Loudness Normalizer AudioLab detects every audio and video playing across your browser and gives you control over all of it from one place — without leaving the page you're on. It hooks into the Web Audio pipeline to compute real-time audio metrics and apply automatic loudness normalization. FEATURES • Cross-Tab Media Detection — Automatically finds all unmuted audio and video across every open tab. Shows the media name, source type, and playback state. • Real-Time Audio Metrics — Computes windowed RMS, peak amplitude, and dBFS in an AudioWorklet on the audio render thread. Displayed live on each media card. • Audio Classification — Labels each playing element in real time: Silent, Quiet, Normal, or Loud. Uses smoothed dBFS to prevent jitter. • Loudness Normalization — Automatic gain adjustment to bring all audio to a target loudness. Uses attack/release smoothing, a max gain cap, and clipping protection. Adjustable target via slider. Works across all tabs. • Audio Focus Stack — Start playing audio in a new tab and the previous tab's audio automatically pauses. When the new audio stops, the previous one resumes. Disabled by default. • Remote Play/Pause — Control any tab's audio directly from the overlay or popup without switching tabs. • Click-to-Jump — Click any media card to instantly switch to that tab. • Persistent Overlay — A draggable, collapsible overlay showing all media with live dB levels and controls. Disabled by default. • Keyboard Shortcuts — Alt+Shift+P to play/pause, Alt+Shift+J to jump to the playing tab. Customizable at chrome://extensions/shortcuts. • Persistent Settings — All preferences are saved and restored automatically when the browser restarts. PRIVACY AudioLab does not collect, transmit, or share any data. All audio processing happens locally on your device. Settings are stored locally via chrome.storage.local.
