Fix audio and video delay caused by Bluetooth latency. Sync your sound perfectly on YouTube, Netflix, and more. Fix Bluetooth audio delay on your favorite streaming sites. Bluetooth headphones often suffer from latency, causing the audio to fall out of sync with the video. LagSync is a technical tool designed to fix this by letting you adjust the audio or video offset in real-time. While primarily tested and optimized for YouTube and Netflix, LagSync is built to work on all standard HTML5 video players to ensure a synchronized viewing experience. Main Features: • Real-time sync: Shift the audio offset instantly without refreshing the page. • Broad compatibility: Optimized for YouTube, Netflix, and most other HTML5 video players. • Precision control: Fine-tune the delay in milliseconds for exact synchronization. • Privacy first: No tracking or data collection. All settings stay locally in your browser. • Performance focused: Minimal code that won't slow down your tabs or drain your battery. How it works: 1. Open a video in your browser. 2. Click the LagSync icon in the toolbar. 3. Use the slider or input fields to adjust the offset until the sync is correct. Why LagSync? Most video players lack built-in tools for audio delay compensation. LagSync provides a straightforward, manual solution for users who want their audio and video to match perfectly.
