Sync your Audio
on Twitch
Bluetooth latency makes Twitch impossible to watch. LagSync fixes the delay at the engine level for perfect lip-sync.
Twitch is a live, variable-bitrate platform with frequent scene and overlay changes — this increases the chance of transient desyncs.

Quick Setup Guide
Install & Pin
Add LagSync to your browser and pin it to your toolbar for quick access while watching.
Play Twitch
Open any video on Twitch. LagSync will automatically detect the video engine and prepare the hook.
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.
Practical Tips
Twitch is a live, variable-bitrate platform with frequent scene and overlay changes — this increases the chance of transient desyncs.
- Use a baseline preset of 200–250 ms for live streams; lower values risk underflow when frames drop.
- Use the canvas / live-edge pipeline when available — it is more robust across overlays and dynamic frame updates (may increase CPU usage).
- Force a single player quality if you see stuttering after auto-transcodes.
- Reduce CPU load (hide chat, close background tabs) if stuttering correlates with high CPU usage.
