Optimized for YouTube
Sync your Audio
on YouTube
Bluetooth latency makes YouTube impossible to watch. LagSync fixes the delay at the engine level for perfect lip-sync.
Quick Setup Guide
1
Install & Pin
Add LagSync to your browser and pin it to your toolbar for quick access while watching.
2
Play YouTube
Open any video on YouTube. LagSync will automatically detect the video engine and prepare the hook.
3
Slide to Sync
Open the popup and move the slider. Your audio will shift in real-time until it fits the video perfectly. You could also use our built in latency tester.
Pro Tip for YouTube Users
"YouTube often uses high-bitrate AAC. If the lag feels inconsistent, try a fixed preset like 180ms."
Coming Soon
LagSync v1.0 is on the way. Stay tuned for the official release across all major browsers.
