FIR Convolver + A/V Sync 作者： Omri V
Applies a stereo pair of FIR impulse responses (separate Left/Right) to every video and audio player on every site, and delays the video image to compensate for the FIR's latency. Resource-intensive by nature: real-time convolution plus full-quality

关于此扩展
Play every video and song through YOUR OWN speaker/room correction — and keep the picture perfectly in sync with the sound. Load your filters once and forget it.
🎧 YOUR CORRECTION, EVERYWHERE
- Real-time stereo FIR convolution on every HTML5 video and audio, from your own WAVs — two mono or one stereo, any rate, even 262,144 taps @ 192 kHz.
🎬 PERFECT LIP-SYNC
- The picture is held back by the filter's exact latency, corrected live for vsync, player skew and audio-pipeline lag.
🌈 HDR PASSTHROUGH
- HDR / 10-bit video is delayed through a native shadow player, not an 8-bit canvas, so HDR is preserved — local files and streaming (like YouTube).
⚡ LOW-LATENCY EQ MODE
- A ~0 ms EQ built from your filter's response, for players the full convolution can't run on — or on everything with the master off.
🎚 AUTO LATENCY DETECTION
- Peak / onset / centroid, exact to 0.01 ms, with 1×–16× latency reduction and a before→after impact panel.
🖥 FULL-QUALITY PICTURE
- GPU zero-copy delay — never downscaled.
🔊 SPEAKERS VS HEADPHONES
- Process only on your speakers, bypass on headphones (optional Windows watcher for instant device-switch detection).
🛠 EXTRAS
- Built-in sync calibrator, periodic resync for long sessions, per-site on/off, and a safety limiter.
🏷 AT-A-GLANCE TOOLBAR BADGE
- ON, EQ, HDR, NOT or OFF tells you exactly what each tab is doing (full legend in Settings).
─────────────────────────────
✅ WORKS ON
- YouTube, Twitch, Vimeo, embedded players, and direct/local video & audio files — anything HTML5.
🚫 CAN'T TOUCH
- DRM video (Netflix, Disney+, Prime Video) — encrypted and unreachable by ANY extension — and cross-origin media without CORS. These are auto-detected and left completely untouched, never broken.
📦 YOU'LL NEED
- Your own FIR correction WAVs (from REW, rePhase, Acourate…). Nothing is bundled. Real-time convolution plus full-quality video buffering is demanding — a capable CPU/GPU keeps playback smooth. The device watcher is Windows-only.
🌈 HDR NOTE
- HDR passthrough targets Firefox 153 (beta). Firefox's HDR engine is new and still buggy — e.g. HDR colors can corrupt after switching tabs (a Firefox bug cleared by restarting Firefox, not caused by this extension). The extension also works around a Firefox bug where fullscreen HDR dims when the player controls hide.
