LagSync - Bluetooth Audio Fix par Simon

Fix Bluetooth audio delay on YouTube, Netflix, and more. Adjust sync in real-time for perfect lip-sync with your headphones.

STOP THE LIP-SYNC FRUSTRATION

Bluetooth headphones often suffer from noticeable 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 optimized for YouTube and Netflix, LagSync is built to work on almost all standard HTML5 video players to ensure a perfectly synchronized viewing experience.

MAIN FEATURES

• Real-time Sync: Shift the audio offset instantly without refreshing the page or re-buffering.
• Broad Compatibility: Specialized hooks for major streaming platforms and universal support for HTML5 video.
• Precision Control: Fine-tune the delay in milliseconds (ms) for exact synchronization.
• Performance Focused: Minimal code footprint that won't slow down your tabs or drain your battery.

HOW IT WORKS

1. Open a video in your Firefox browser.
2. Click the LagSync icon in your toolbar.
3. Adjust the slider or input a specific millisecond value until the sync is perfect.

PRIVACY FIRST

Firefox users value their data, and so do we.

• Zero Tracking: We do not collect, store, or transmit your browsing history or video data.
• Local Storage: All your settings and offsets stay locally in your browser.
• No Ads: LagSync is a utility tool, not an ad-delivery platform.

WHY LAGSYNC?

Most web players lack built-in tools for audio delay compensation. LagSync provides a straightforward, manual solution for users who want their media to match their audio perfectly—no matter what headphones they are using.
